function ArcTan(const Number Extended):Extended;
The ArcTan function is a mathematical function giving the value in radians of the Arc Tangent of Number.
PI radians = 180 degrees
Example:
- TRObject Syntax
var
floatValue : single;
const
PI = 3.14;
{
// The ArcTan of PI/2 should give 1.0
floatValue = ArcTan(PI/2);
ShowMessage('ArcTan of PI/2 = '+FloatToStr(floatValue));
}
- Base Syntax
var
floatValue : single;
const
PI = 3.14;
begin
// The ArcTan of PI/2 should give 1.0
floatValue := ArcTan(PI/2);
ShowMessage('ArcTan of PI/2 = '+FloatToStr(floatValue));
end;
Output:
ArcTan of PI/2 = 1,00365507798033
