cexp, cexpf, cexpl − complex exponential function
Math library (libm, −lm)
#include <complex.h>
double
complex cexp(double complex z);
float complex cexpf(float complex z);
long double complex cexpl(long double complex
z);
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)
