<![CDATA[
function Cos ( const Number : Extended ) : Extended;
Description
The Cos function is a mathematical function giving the Cosine value of a Number value given radians.
PI radians = 180 degrees
Notes
The System unit supports only the following angular functions:
ArcTan
Sin
Cos
Related commands
ArcCos The Arc Cosine of a number, returned in radians
ArcSin The Arc Sine of a number, returned in radians
ArcTan The Arc Tangent of a number, returned in radians
Sin The Sine of a number
Tan The Tangent of a number
Example code : Get the Cosine of 60 degrees
var
float : single;
begin
// The Sine of 60 degrees = 0.5
float := Cos(PI/3); // = 180/3 = 60 degrees
ShowMessage('Cos(PI/3) = '+FloatToStr(float));
end;
