Introduction to Logical Operations
Introduction to Logical Operations
Introduction to Conditions
Overview
We previously mentioned that you can perform various types of operations on values and variables. Sometimes, before performing an operation, you want to examine one or more conditions. The reason is that you want to find out whether a certain condition is true or false and then proceed based on the result of that condition.
When you perform a comparison, such as between two numbers, you probably want to find whether those numbers are the same, whether they are different, or one is greater than the other. To perform such a comparison, you use two operands and an operator as in the following formula:
operand1 operator operand2
This is the basic formula of a Boolean expression.
Introduction to Boolean Values
A value is said to be Boolean if it is true or it is false. In fact, the two available Boolean values are $true and $false.
To declare a Boolean variable, start with $ followed by a letter or a combination of characters that start with a letter. To initialize a Boolean variable, assign $true or $false to it. Here is an example:
$drinkingUnderAge = $true
Presenting a Boolean Value
To display the value of a Boolean variable, you can type its name at the PowerShell prompt or at the terminal of Visual Studio Code. Here are examples:
Assigning a Logical Expression to a Boolean Variable
We saw that, to initialize or specify the value of a Boolean variable, you can assign a $true or $false value to it. A Boolean variable can also be initialized with a Boolean expression. This would be done as follows:
Boolean-variable = operand1 Boolean-operator operand2
To make your code easy to read, you should include the logical expression in parentheses. This can be done as follows:
Boolean-variable = (operand1 Boolean-operator operand2);
If a Condition Applies
The primary formula to perform a comparison is with an operator named if. The primary formula to use it is:
if(condition) { statement }
The condition can have the following formula:
operand1 Boolean-operator operand2
Any of the operands can be a constant or the name of a variable. The operator is a logical one. The whole expression is the condition. If the expression produces a true result, then the statement would execute.
The Body of a Conditional Statement
The statement is called the body of the conditional statement. It must start with an opening curly bracket "{" and end with a closing curly bracket "}". This would be done as follows:
if( operand1 operator operand2) { . . . . . . . . . }
In this case, the section from { (included) to } (included) is referred to as the body of the conditional statement.
Fundamentals of Logical Operators
Introduction
As introduced in previous sections, a logical comparison is used to establish the logical relationship between two values, a variable and a value, or two variables. There are various operators available to perform such comparisons. Consider the following code from a file named Exercise.ps1:
[string]$firstName = 'Michael' [string]$lastName = 'Carlock' [float]$hSalary = 24.77 [float]$timeWorked = 38.50 [float]$netPay = $hSalary * $timeWorked Write-Host '===============================' Write-Host 'Payroll Evaluation' Write-Host '===============================' Write-Host 'Employee Information' Write-Host '-------------------------------' Write-Host "Full Name: $firstName $lastName" Write-Host "Hourly Salary: $hSalary" Write-Host '===============================' Write-Host "Time Worked: $timeWorked" Write-Host "Net Pay: $netPay" Write-Host '==============================='
This would produce:
PS C:\Windows\System32> C:\Exercises\Conditions.ps1 =============================== Payroll Evaluation =============================== Employee Information ------------------------------- Full Name: Michael Carlock Hourly Salary: 24.77 =============================== Time Worked: 38.5 Net Pay: 953.645 ===============================
To compare two values or two variables for equality, you can use an operator named -eq. The formula to use it is:
value1 -eq value2
The equality operation is used to find out whether two variables (or one variable and a constant) hold the same value. Here is an example:
[ushort]$startingSalary = 34000
[string]$employmentStatus = "Full-Time"
if($employmentStatus -eq "Full-Time") {
$startingSalary = 40000
}
Write-Host 'Employee Record'
Write-Host '----------------------------------'
Write-Host 'Employment Status: ' $employmentStatus
Write-Host 'Starting Yearly Salary:' $startingSalary
Write-Host '=================================='
This would produce:
PS C:\Windows\System32> C:\Exercises\Conditions.ps1 Employee Record ---------------------------------- Employment Status: Full-Time Starting Yearly Salary: 40000 ==================================
A Difference in Values
To find out whether two values are different, use an operator named -ne. Here is an example:
$certification = "y"
$employmentStatus = "Hired"
if($certification -ne "y") {
$employmentStatus = "This employment requires a security certification. We will get back to you."
}
Write-Host '=================================================='
Write-Host 'Employment Verification'
Write-Host '--------------------------------------------------'
Write-Host "Candition holds certification:" $certification
Write-Host "Decision Status: " $employmentStatus
Write-Host '=================================================='
This would produce:
PS C:\Windows\System32> C:\Exercises\Conditions.ps1 ================================================== Employment Verification -------------------------------------------------- Candition holds certification: y Decision Status: Hired ==================================================
A Value Less Than Another
To find out whether one value is lower than another, you use an operator named -lt. Here are examples:
[ubyte]$discountRate = 75 [string]$itemName = 'Pleated Red Dress' [float]$originalPrice = 224.95 [ubyte]$daysInStore = 45 if($daysInStore -lt 60) { $discountRate = 50 } if($daysInStore -lt 45) { $discountRate = 35 } if($daysInStore -lt 35) { $discountRate = 15 } if($daysInStore -lt 15) { $discountRate = 0 } $discountAmount = $originalPrice * $discountRate / 100 $discountedPrice = $originalPrice - $discountAmount Write-Host '=======================================================' Write-Host 'Store Inventory' Write-Host '-------------------------------------------------------' Write-Host "Item Name: " $itemName Write-Host "Original Price: " $originalPrice Write-Host "Days in Store: " $daysInStore Write-Host "Discount Rate: " $discountRate% Write-Host "Discount Amount: " $discountAmount Write-Host "Discounted Price:" $discountedPrice Write-Host '======================================================='
This would produce:
PS C:\Windows\System32> C:\Exercises\Conditions.ps1 ========================= Store Inventory ------------------------------------- Item Name: Pleated Red Dress Original Price: 224.95 Days in Store: 45 Discount Rate: 50% Discount Amount: 112.475 Discounted Price: 112.475 =========================
A Value Less Than Or Equal To Another
To find out whether a certain value is less than or equal to another, you use an operator named -le. Here is an example:
$firstName = "Catherine" $lastName = "Busbey" $hSalary = 24.37 #Time Worked" $monday = 9.5 $tuesday = 8 $wednesday = 10.5 $thursday = 9.5 $friday = 10 $timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday $regTime = 40.00 $regPay = $hSalary * 40.00 $overtime = $timeWorked - 40.00 $overPay = $hSalary * 1.50 * $overtime if($timeWorked -le 40.00) { $regTime = $timeWorked $regPay = $hSalary * $timeWorked $overtime = 0.00 $overPay = 0.00 } $netPay = $regPay + $overPay Write-Host '=========================================' Write-Host 'Payroll Evaluation' Write-Host '=========================================' Write-Host 'Employee Information' Write-Host '-----------------------------------------' Write-Host "Full Name: $firstName $lastName}" Write-Host "Hourly Salary: $hSalary" Write-Host '=========================================' Write-Host 'Time Worked Summary' Write-Host '-----------------------------------------' Write-Host "Monday: $monday" Write-Host "Tuesday: $tuesday" Write-Host "Wednesday: $wednesday" Write-Host "Thursday: $thursday" Write-Host "Friday: $friday" Write-Host '=========================================' Write-Host ' Pay Summary' Write-Host '-----------------------------------------' Write-Host ' Time Pay' Write-Host '-----------------------------------------' Write-Host " Regular: $regTime $regPay" Write-Host '-----------------------------------------' Write-Host " Overtime: $overtime $overPay" Write-Host '=========================================' Write-Host " Net Pay: $netPay" Write-Host '========================================='

A Value Greater Than Another: >
To find out if one value is greater than the other, you use an operator named -gt. The formula to use it is:
value1 -gt value2
Both operands, in this case value1 and value2, can be variables or the left operand can be a variable while the right operand is a constant. If the value on the left of the -gt operator is greater than the value on the right side or a constant, the comparison produces a True result. Otherwise, the comparison renders False. Here is an example:
$firstName = "Catherine" $lastName = "Busbey" $hSalary = 24.37 #Time Worked" $monday = 7 $tuesday = 8 $wednesday = 6.5 $thursday = 8.5 $friday = 6.5 $timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday $regTime = $timeWorked $overtime = 0.00 $overPay = 0.00 $regPay = $hSalary * $timeWorked if($timeWorked -gt 40.00) { $regTime = 40.00 $regPay = $hSalary * 40.00 $overtime = $timeWorked - 40.00 $overPay = $hSalary * 1.50 * $overtime } $netPay = $regPay + $overPay Write-Host '=========================================' Write-Host 'Payroll Evaluation' Write-Host '=========================================' Write-Host 'Employee Information' Write-Host '-----------------------------------------' Write-Host "Full Name: $firstName $lastName" Write-Host "Hourly Salary: $hSalary" Write-Host '=========================================' Write-Host 'Time Worked Summary' Write-Host '-----------------------------------------' Write-Output "Monday: $monday" Write-Output "Tuesday: $tuesday" Write-Output "Wednesday: $wednesday" Write-Output "Thursday: $thursday" Write-Output "Friday: $friday" Write-Host '=========================================' Write-Host ' Pay Summary' Write-Host '-----------------------------------------' Write-Host ' Time Pay' Write-Host '-----------------------------------------' Write-Output " Regular: $regTime $regPay" Write-Output '-----------------------------------------' Write-Output " Overtime: $overtime $overPay" Write-Output '=========================================' Write-Output " Net Pay: $netPay" Write-Host '========================================='

A Value Greater Than or Equal to Another
To find out whether one value is greater than or equal to another, you can use an operator named -ge, read the "greater than or equal to" operator. The formula it follows is:
value1 -ge value2
The comparison is performed on both operands: value1 and value2:
Options on Conditional Statements
if a Condition is True
One way to formulate a conditional statement is to find out whether a situation is true or false. In this case, one of the operands must be a Boolean value as $true or $false. The other operand can be a Boolean variable. One of the operands can also be an expression that holds a Boolean value.
Imagine that you want to evaluate the condition as being true. Here is an example:
$firstName = "Catherine"
$lastName = "Busbey"
$hSalary = 24.37
$employeeIsFullTime = $true
#Time Worked"
$monday = 9
$tuesday = 8
$wednesday = 10.5
$thursday = 9.5
$friday = 8.5
$timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday
$regTime = $timeWorked
$regPay = $hSalary * $timeWorked
$overtime = 0.00
$overPay = 0.00
if($employeeIsFullTime -eq $true) {
$regTime = 40.00
$regPay = $hSalary * 40.00
$overtime = $timeWorked - 40.00
$overPay = $hSalary * 1.50 * $overtime
}
$netPay = $regPay + $overPay

If a Boolean variable is (currently) holding a true value (at the time you are trying to access it), when you are evaluating the expression as being $true, you can omit the -eq $true or the $true -eq expression in your statement. Therefore, the above expression can be written as follows:
. . .
$timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday
$regTime = $timeWorked
$regPay = $hSalary * $timeWorked
$overtime = 0.00
$overPay = 0.00
if($employeeIsFullTime) {
$regTime = 40.00
$regPay = $hSalary * 40.00
$overtime = $timeWorked - 40.00
$overPay = $hSalary * 1.50 * $overtime
}
$netPay = $regPay + $overPay
. . .
This would produce the same result as previously.
Negating a Condition
Consider the following code:
$firstName = "Catherine" $lastName = "Busbey" $hSalary = 24.37 $employeeIsFullTime = $false #Time Worked" $monday = 10 $tuesday = 9 $wednesday = 8.5 $thursday = 10.5 $friday = 8 $timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday $regTime = $timeWorked $regPay = $hSalary * $timeWorked $overtime = 0.00 $overPay = 0.00 if($employeeIsFullTime) { $regTime = 40.00 $regPay = $hSalary * 40.00 $overtime = $timeWorked - 40.00 $overPay = $hSalary * 1.50 * $overtime } $netPay = $regPay + $overPay Write-Host '======================================' Write-Output 'Payroll Evaluation' Write-Host '======================================' Write-Output 'Employee Information' Write-Host '--------------------------------------' Write-Output "Full Name: $firstName $lastName" Write-Host "Hourly Salary: $hSalary" Write-Output '======================================' Write-Host 'Time Worked Summary' Write-Output '--------------------------------------' Write-Host "Monday: $monday" Write-Output "Tuesday: $tuesday" Write-Host "Wednesday: $wednesday" Write-Output "Thursday: $thursday" Write-Host "Friday: $friday" Write-Output '======================================' Write-Host 'Pay Summary' Write-Output '--------------------------------------' Write-Host 'Regular Time: ' $regTime Write-Output '--------------------------------------' Write-Host 'Regular Pay: ' $regPay Write-Output '--------------------------------------' Write-Host 'Over Time: ' $overtime Write-Output '--------------------------------------' Write-Host 'Overtime Pay: ' $overPay Write-Output '======================================' Write-Host "Net Pay: $netPay" Write-Output '======================================'
This would produce:

If you have a logical expression or value, to let you get its logical opposite, you can use an operator represented by !. The formula to use it is:
!variable-or-expression
Actually there are various ways you can use the ! logical operator. The classic way is to check whether a variable is not holding a True value. To do this, use an if() conditional statement and precede the name of the variable with the exclamation point. Here is an example:
$firstName = "Catherine"
$lastName = "Busbey"
$hSalary = 24.37
$employeeIsFullTime = $false
#Time Worked"
$monday = 10
$tuesday = 9
$wednesday = 8.5
$thursday = 10.5
$friday = 8
$timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday
$regTime = $timeWorked
$regPay = $hSalary * $timeWorked
$overtime = 0.00
$overPay = 0.00
if(!$employeeIsFullTime) {
$regTime = 40.00
$regPay = $hSalary * 40.00
$overtime = $timeWorked - 40.00
$overPay = $hSalary * 1.50 * $overtime
}
$netPay = $regPay + $overPay

Another way to use the exclamation point is the precede a variable with that operator and assign it to a Boolean variable.
Besides the exclamation point, another way to chec the opposite of a variable is by using an operator named -not. You use both operators practically interchangeably. Here are examples:
[string]$firstName = "Catherine"
[string]$lastName = "Busbey"
[float]$hSalary = 24.37
[bool]$employeeIsFullTime = $false
#Time Worked"
[float]$monday = 10
[float]$tuesday = 9
[float]$wednesday = 8.5
[float]$thursday = 10.5
[float]$friday = 8
$timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday
[float]$regTime = $timeWorked
[float]$regPay = $hSalary * $timeWorked
[float]$overtime = 0.00
[float]$overPay = 0.00
if(-not $employeeIsFullTime) {
$regTime = 40.00
$regPay = $hSalary * 40.00
$overtime = $timeWorked - 40.00
$overPay = $hSalary * 1.50 * $overtime
}

If you are using a conditional operator such as the if operator we have encountered so far, and you are using one of the Boolean operators we have used so far (-eq, -ne, -lt, -le, -gt, or -ge), you can first apply the -not operator on the variable. Here is an example:
$firstName = "Catherine"
$lastName = "Busbey"
$hSalary = 24.37
$employeeIsFullTime = $true
#Time Worked"
$monday = 9
$tuesday = 8
$wednesday = 10.5
$thursday = 9.5
$friday = 8.5
$timeWorked = $monday + $tuesday + $wednesday + $thursday + $friday
$regTime = $timeWorked
$regPay = $hSalary * $timeWorked
$overtime = 0.00
$overPay = 0.00
if(-not $employeeIsFullTime -eq $true) {
$regTime = 40.00
$regPay = $hSalary * 40.00
$overtime = $timeWorked - 40.00
$overPay = $hSalary * 1.50 * $overtime
}
