SQRT(3)                   OpenBSD Programmer's Manual                  SQRT(3)

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

SYNOPSIS
     #include <math.h>

     double
     cbrt(double x);

     float
     cbrtf(float x);

     double
     sqrt(double x);

     float
     sqrtf(float x);

DESCRIPTION
     The cbrt() function computes the cube root of x.  The cbrtf() function is
     a single 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().

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