CEXP

NAME

cexp, cexpf, cexpl − complex exponential function

#include <complex.h>

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

Link with −lm.

The function calculates e (2.71828..., the base of natural logarithms) raised to the power of z.

One has cexp(I*z) = ccos(z) + I*csin(z).
