NAME
     creal, crealf, creall - complex real functions

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     double creal(double complex z);


     float crealf(float complex z);

DESCRIPTION
     These functions compute the real part of z.

RETURN VALUES
     These functions return the real part value.

ERORS
     No errors are defined.

USAGE
     For a variable z of complex type:

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