NAME

6       cexp, cexpf, cexpl - complex exponential function
7

LIBRARY

9       Math library (libm, -lm)
10

SYNOPSIS

12       #include <complex.h>
13
14       double complex cexp(double complex z);
15       float complex cexpf(float complex z);
16       long double complex cexpl(long double complex z);
17

DESCRIPTION

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