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
.
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 first appeared in glibc in version 2.1.
