Performs the trigonometric arc sine operation on Param and returns an angle in the range from -PI/2 to PI/2 expressed in radians.

Parameters

Param

Value between -1 and 1 whose arcsine has to be calculated.

 

Return Value

Arcsine of Param

Example Code

// Calculate arcsine of 0.5. PI is defined internally by SSEdit
double Res = asin(0.5) * 180 / PI;
