CASINH(3M) Mathematical Library Functions CASINH(3M)

casinh, casinhf, casinhl - complex arc hyperbolic sine functions

double complex casinh(double complex z);

float complex casinhf(float complex z);

long double complex casinhl(long double complex z);

These functions compute the complex arc hyperbolic sine of z, with branch cuts outside the interval [ -i, +i] along the imaginary axis.

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 [ −ipi/2, +ipi/2 ] along the imaginary axis.

No errors are defined.
