Defined in header <cmath>
float       cbrt( float arg );		(C++11 feature)
double      cbrt( double arg );		(C++11 feature)
long double cbrt( long double arg );		(C++11 feature)

Computes cubic root of arg.

[edit] Parameters

arg

-

floating point value

[edit] Return value

cubic root of arg.

Domain error occurs if arg is negative. NAN is returned in that case.
