+FUNCTION
+ <<cimag>>, <<cimagf>>---imaginary part

+INDEX

+
+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
