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

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

SEE ALSO
     math(3)

STANDARDS
     The sqrt() function conforms to ANSI X3.159-1989 (``ANSI C89'').

HISTORY
     The cbrt() function appeared in 4.3BSD.
