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 logarithms) 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.
