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