NAME
     cceexxpp - complex exponential function

SYNOPSIS
     ##iinncclluuddee <>

     double complex
     cceexxpp(double complex z);

     long double complex
     cceexxppll(long double complex z);

     float complex
     cceexxppff(float complex z);

DESCRIPTION
     cceexxpp(z) returns the complex exponential of z.

     cexp(conj(z)) = conj(cexp(z)), for all complex floating-point numbers z.

SSPPEECCIIAALL VVAALLUUEESS
     The conjugate symmetry of cexp() is used to abbreviate the specification
     of special values.

     cceexxpp(+-0 + 0i) returns 1 + 0i.

     cceexxpp(x + inf i) returns NaN + NaN i, and raises the invalid flag, for
     finite x.

     cceexxpp(x + NaN i) returns NaN + NaN i, for finite x.

     cceexxpp(inf + 0i) returns inf + 0i.

     For the following two cases, cis(y) denotes cos(y) + I*sin(y).

     cceexxpp(-inf + yi) returns 0*cis(y), for finite y.

     cceexxpp(inf + yi) returns inf*cis(y), for finite nonzero y.

     cceexxpp(-inf + inf i) returns -0 + 0i.

     cceexxpp(inf + inf i) returns -inf + NaN i, and raises the invalid flag.

     cceexxpp(-inf + NaN i) returns -0 + 0i.

     cceexxpp(inf + NaN i) returns -inf + NaN i.

     cceexxpp(NaN + 0i) returns NaN + 0i.

     cceexxpp(NaN + yi) returns NaN + NaN i for all nonzero numbers y.

     cceexxpp(NaN + NaN i) returns NaN + NaN i.
