cexp(3) — complex exponential function

cexp(3)

Library Functions Manual

cexp(3)

NAME

cexp, cexpf, cexpl - complex exponential function

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)

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