sqrt(3) Library Functions Manual sqrt(3)
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.
