acos (Math.acos method)

public static acos(x:Number) : Number
Computes and returns the arc cosine of the number specified in the parameter
Availability: ActionScript 1.0; Flash Player 5 - In Flash Player 4, the methods and properties
of the Math class are emulated using approximations and might not be as accurate as the non-
emulated math functions that Flash Player 5 supports.
Parameters
- A number from -1.0 to 1.0.
x:Number
Returns
- A number; the arc cosine of the parameter
Number
Example
The following example displays the arc cosine for several values.
trace(Math.acos(-1)); // output: 3.14159265358979
trace(Math.acos(0)); // output: 1.5707963267949
trace(Math.acos(1)); // output: 0
