cexp (3) Linux Manual Page
cexp, cexpf, cexpl – complex exponential function
Synopsis
#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.
Description
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)
Versions
These functions first appeared in glibc in version 2.1.Attributes
