    Alpha only.

    Format

      #include  <complex.h>

      double complex cexp  (double complex z);

      float complex cexpf  (float complex z);

      long double complex cexpl  (long double complex z);

1 - Argument

 z

    A complex value.

2 - Description

    The cexp functions compute the complex exponential value of
    z, defined as e**z, where e is the constant used as a base for
    natural logarithms.

3 - Return Values

    x                  The complex exponential value of the argument.
