NAME

   cexp, cexpf, cexpl - complex exponential function

SYNOPSIS

   #include <complex.h>

   double complex cexp(double complex z);
   float complex cexpf(float complex z);
   long double complex cexpl(long double complex z);

DESCRIPTION

   These   functions   calculate   e  (2.71828...,  the  base  of  natural
   logarithms) raised to the power of z.

   One has:

       cexp(I * z) = ccos(z) + I * csin(z)
