SQRT(3)               DragonFly Library Functions Manual               SQRT(3)

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

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() function computes the cube root of x.  The cbrtf() function is
     a single precision version of cbrt().  The cbrtl() function is an
     extended precision version of cbrt().

     The sqrt() function computes the non-negative square root of x.  The
     sqrtf() function is a single precision version of sqrt().  The sqrtl()
     function is an extended precision version of sqrt().

RETURN VALUES
     If x is negative, sqrt(x), sqrtf(x) and sqrtl(x) set the global variable
     errno to EDOM.

HISTORY
     A sqrt() function first appeared in Version 3 AT&T UNIX.

     The cbrt() function appeared in 4.3BSD.
