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);
  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.
