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 The function calculates e (2.71828..., the base of natural logarithms) raised to the power of z.

One has:

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