NAME
       creal, crealf, creall - complex real functions

SYNOPSIS
       cc [ flag... ] file... -lm [ library... ]
       #include <complex.h>

       double creal(double complex z);

       float crealf(float complex z);

       long double creall(long double complex z);

DESCRIPTION
       These functions compute the real part of z.

RETURN VALUES
       These functions return the real part value.

ERRORS
       No errors are defined.

USAGE
       For a variable z of complex type:

       z == creal(z) + cimag(z)*I
