cexp(3) | Library Functions Manual | cexp(3) |
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 attributes(7).
