Cos

function Cos(const X: Extended): Extended;

Calculates the cosine of an angle.
In Clomosy code, Cos returns the cosine of the angle X.
X is a real-type expression that represents an angle in radians.
PI radians = 180 degrees

Example

var
   floatValue : single;
 
 const
   PI = 3.14;
 
 {
   // The Sine of 60 degrees = 0.5
   floatValue = Cos(PI/3);  // = 180/3 = 60 degrees
   ShowMessage('Cos(PI/3) = '+FloatToStr(floatValue));
 }

Output:

Cos(PI/3) = 0,500459689008206
