NAME

cexp, cexpf, cexpl - complex exponential function

LIBRARY

Math library (libm, -lm)

SYNOPSIS

#include <complex.h>

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

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 were added in glibc 2.1.
