Return type: opaque Returns: The arc cosine of the floating point value. |
export external float function acos value float x
A trigonometric function that calculates, in radians, the arc cosine (inverse cosine) of a floating point number. This function works the same way as its equivalent in the C math library.
Out-of-range values, (|x| > 1), return "not a number" (NaN).
