MathArcsin

The function returns the arc sine of x within the range of -π/2 to π/2 radians.

Parameters

val

[in]   The val value between -1 and 1, the arc sine of which is to be calculated.

Return Value

Arc sine of the val number in radians within the range of -π/2 to π/2 radians. If val is less than -1 or more than 1, the function returns NaN (indeterminate value).
