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.

NAME
cbrt, cbrtf, cbrtl, sqrt, sqrtf, sqrtl -- cube root and square root functions

LIBRARY
Math Library (libm, -lm)

SYNOPSIS
#include <math.h>

double
cbrt(double x);

float
cbrtf(float x);

long double
cbrtl(long double x);

double
sqrt(double x);

float
sqrtf(float x);

long double
sqrtl(long double x);

DESCRIPTION
The cbrt(), cbrtf(), and cbrtl() functions compute the cube root of x.

The sqrt(), sqrtf(), and sqrtl() functions compute the non-negative square root of x.

RETURN VALUES
The cbrt(), cbrtf(), and cbrtl() functions return the requested cube root.  The sqrt(), sqrtf(), and sqrtl() functions return the requested
square root unless an error occurs.  An attempt to take the sqrt() of negative x raises an invalid exception and causes an NaN to be returned
(except that the square root of -0 is valid and equal to -0.)
