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:
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
