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