cexp

(3)

complex exponential function

Library functionsmanpages-dev 6.9.1-1also documents cexpf, cexpl

#include <complex.h> double complex cexp(double complex z); float complex cexpf(float complex z); long double complex cexpl(long double complex z);

LIBRARY

Math library (libm, -lm)

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).
