sqrt(3)
NAME
  sqrt, cbrt - Square and cube root functions

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 );

LIBRARY
  Math Library (libm)

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.
