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)
These functions were added in glibc 2.1.
For an explanation of the terms used in this section, see
