cexp(3) Library Functions Manual cexp(3) NAME cexp, cexpf, cexpl - complex exponential function LIBRARY Math library (libm, -lm) SYNOPSIS #include <complex.h> double complex cexp(double complex z); float complex cexpf(float complex z); long double complex cexpl(long double complex z); 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 were added in glibc 2.1.
