Concept Framework 1.0 documentation

standard.C.math.acos

Name	Version	Deprecated
acos	version 1.0	no

Prototype:

number acos(number cosine)

Parameters:

cosine

[in] Value whose arccosine is to be calculated, where -1 <= cosine <= 1.

Description:

Returns the arccosine of cosine in the range 0 to M_PI/2 radians.
If cosine is less than -1 or greater than 1, acos returns an indefinite by default.

Example:

import standard.C.math



class Main {

     function Main() {

          var x = 0;

          echo "Arcsine of " + x + " is " + asin(x) + "\n";

          echo "Arccosine of " + x + " is " + acos(x);

     }

} 

 



Results 

Arcsine of 0 is 0

Arccosine of 0 is 1.5707963267948966

Returns:
Returns the arccosine of cosine in the range 0 to M_PI/2 radians.
