acos

warning

This function starts with a lowercase letter.

Description​

Get the inversed value of a cosine in degrees. In trigonometrics, arc cosine is the inverse operation of cosine.

NameDescription
Float:valuevalue whose arc cosine is computed, in the interval [-1,+1].

Returns​

The angle in degrees, in the interval [0.0,180.0].

Examples​

//The arc cosine of 0.500000 is 60.000000 degrees.

public OnGameModeInit()
{
    new Float:param, Float:result;
    param = 0.5;
    result = acos(param);
    printf("The arc cosine of %f is %f degrees.", param, result);
    return 1;
