NAME

6       cexp, cexpf, cexpl - complex exponential function
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex cexp(double complex z);
12       float complex cexpf(float complex z);
13       long double complex cexpl(long double complex z);

DESCRIPTION

18       These  functions  calculate  e  (2.71828...,  the base of natural loga‐
19       rithms) raised to the power of z.
20
21       One has:
22
23           cexp(I * z) = ccos(z) + I * csin(z)
24

VERSIONS

26       These functions first appeared in glibc in version 2.1.
