cexp - Man Page

Math library (libm, -lm)

#include <complex.h>

double complex cexp(double complex z);
float complex cexpf(float complex z);
long double complex cexpl(long double complex z);

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)

These functions first appeared in glibc in version 2.1.

For an explanation of the terms used in this section, see attributes(7).

The man pages cexpf(3) and cexpl(3) are aliases of cexp(3).
