cexp, cexpf, cexpl - complex exponential function

  #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.

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)

These functions first appeared in glibc in version 2.1.
