+FUNCTION
+        <<cimag>>, <<cimagf>>---imaginary part
+
+INDEX
+        cimag
+INDEX
+        cimagf
+
+ANSI_SYNOPSIS
+       #include <complex.h>
+       double cimag(double complex <[z]>);
+       float cimagf(float complex <[z]>);
+
+
+DESCRIPTION
+        These functions compute the imaginary part of <[z]>.
+
+        <<cimagf>> is identical to <<cimag>>, except that it performs
+        its calculations on <<floats complex>>.
+
+RETURNS
+        The cimag functions return the imaginary part value (as a real).
+
+PORTABILITY
+        <<cimag>> and <<cimagf>> are ISO C99
+
+QUICKREF
+        <<cimag>> and <<cimagf>> are ISO C99
