CASINH(3) FreeBSD Library Functions Manual CASINH(3) NAME casinh, casinhf, casinhl - complex arc hyperbolic sine functions SYNOPSIS #include <complex.h> double complex casinh(double complex z); float complex casinhf(float complex z); long double complex casinhl(long double complex z); DESCRIPTION These functions compute the complex arc hyperbolic sine of z, with branch cuts outside the interval [-i, +i] along the imaginary axis. RETURN VALUES These functions return the complex arc hyperbolic sine value, in the range of a strip mathematically unbounded along the real axis and in the interval [-i pi/2, +i pi/2] along the imaginary axis. ERRORS No errors are defined.
