CEXP(3) Linux Programmer's Manual CEXP(3)

cexp, cexpf, cexpl - complex exponential function

#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.

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)

These functions first appeared in glibc in version 2.1.
