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);
       Link with -lm.
DESCRIPTION
       These  functions  calculate  e  (2.71828...,  the base of natural loga-
       rithms) raised to the power of z.
       One has:
           cexp(I * z) = ccos(z) + I * csin(z)
VERSIONS
       These functions first appeared in glibc in version 2.1.
