+FUNCTION

+
+INDEX
+        creal

+        crealf
+INDEX
+        creall
+
+SYNOPSIS
+       #include <complex.h>
+       double creal(double complex <[z]>);
+       float crealf(float complex <[z]>);
+       double long creall(long double complex <[z]>);
+
+       
+DESCRIPTION
+        These functions compute the real part of <[z]>.
+
+        <<crealf>> is identical to <<creal>>, except that it performs
+        its calculations on <<float complex>>.
+
+        <<creall>> is identical to <<creal>>, except that it performs
+        its calculations on <<long double complex>>.
+
+RETURNS
+        The creal* functions return the real part value.
+
+PORTABILITY
+        <<creal>>, <<crealf>> and <<creall>> are ISO C99
+
