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
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.
