NAME
casinh -- complex inverse hyperbolic sine function
SYNOPSIS
double complex casinh(double complex z); long double complex casinhl(long double complex z); float complex casinhf(float complex z);
DESCRIPTION
casinh(z) computes the inverse hyperbolic sine of the complex floating-point number z, with branch cuts outside the interval [-i, i] along the imaginary axis. casinh() returns values in a strip of the complex plane with imaginary part in the interval [-Pi/2, Pi/2]. For all complex floating point numbers z, casinh(conj(z)) = conj(casinh(z)). casinh(-z) = -casinh(z)
SPECIAL VALUES
The symmetries of casinh() are used to abbreviate the specification of special values. casinh(0 + 0i) returns 0 + 0 i. casinh(x + inf i) returns inf + Pi/2 i, for finite positive-signed x. casinh(x + NaN i) returns NaN + NaN i, for finite x. casinh(inf + yi) returns inf + 0i, for finite positive-signed y. casinh(inf + inf i) returns inf + Pi/4 i. casinh(inf + NaN i) returns inf + NaN i. casinh(NaN + 0i) returns NaN + 0i. casinh(NaN + yi) returns NaN + NaN i, for finite y. casinh(NaN + inf i) returns inf + NaN i. casinh(NaN + NaN i) returns NaN + NaN i.
