CTANH(3) Linux Programmer's Manual CTANH(3) NAME ctanh, ctanhf, ctanhl - complex hyperbolic tangent SYNOPSIS #include <complex.h> double complex ctanh(double complex z); float complex ctanhf(float complex z); long double complex ctanhl(long double complex z); Link with -lm. DESCRIPTION These functions calculate the complex hyperbolic tangent of z. The complex hyperbolic tangent function is defined mathematically as: ctanh(z) = csinh(z) / ccosh(z) VERSIONS These functions first appeared in glibc in version 2.1.
