function Tan ( const Number : Extended ) : Extended;
Description
The Tan function is a mathematical function giving the Tangent 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
Cos The Cosine of a number
Sin The Sine of a number
Example code : Get the Tangent of 45 degrees
var
float : single;
begin
// The Tangent of 45 degrees = 1.0
float := Tan(PI/4); // = 180/4 = 45 degrees
ShowMessage('Tan(PI/4) = '+FloatToStr(float));
end;
