DESCRIPTION
The cbrt and the cbrtf functions compute the cube root of x. The sqrt and the sqrtf functions compute the non-negative square root of x.
RETURN VALUES
The cbrt and the cbrtf functions return the requested cube root. The sqrt and the sqrtf functions return the requested square root unless an error occurs. An attempt to take the sqrt of negative x raises an invalid exception and causes an NaN to be returned.
