NAME

sqrt, cbrt − Square and cube root functions

LIBRARY

Math Library (libm.a)

SYNOPSIS

#include <math.h>

double sqrt   (double x);
float  sqrtf  (float  x);
long double sqrtl   (long double x);
double cbrt   (double y);
float  cbrtf  (float  y);
long double cbrtl   (long double y);

DESCRIPTION

sqrt(), sqrtf(), and sqrtl() compute the rounded square root of x.  For platforms supporting a signed zero, sqrt (-0) = 0. 

cbrt(), cbrtf(), and cbrtl() return the rounded cube root of y. 

Function Exceptional Argument Routine Behavior
sqrt(), sqrtf(), sqrtl() x < 0 invalid argument
