Defined in header <cmath>
float       asin( float arg );
double      asin( double arg );
long double asin( long double arg );
double      asin( Integral arg );
(since C++11)

Computes arc sine of arg.

Parameters

arg - floating point value

Return value

Arc sine of arg in radians in the range of [-π/2; π/2] radians.

Domain error occurs if arg is outside the range [-1.0; 1.0]. NAN is returned in that case.
