Math Functions: Degrees To Radius Conversion
Introduction
Extended __fastcall DegToRad(Extended Degrees);
The DegToRad() function is used to calculate the equivalent value of an angle from degrees to radians. This function follows the formula:
2Pi rad = 360˚
which is
1 rad = 360˚ / 2Pi = 180˚ / Pi = 57.3˚
Here is an example:
//--------------------------------------------------------------------------- void __fastcall TForm1::btnConversionClick(TObject *Sender) { Extended Deg = StrToFloat(edtDegrees->Text); Extended Rad = DegToRad(Deg); edtRadians->Text = FloatToStr(Rad); } //---------------------------------------------------------------------------
