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.
