sqrt(3) — Subroutines
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);
double cbrt (double y);
float cbrtf (float y);
DESCRIPTION
sqrt() and sqrtf() compute the rounded square root of x. For platforms supporting a signed zero, sqrt (-0) = 0.
cbrt() and cbrtf() return the rounded cube root of y.
