NAME

12       casinh, casinhf, casinhl - complex arc hyperbolic sine functions
13

SYNOPSIS

15       #include <complex.h>
16
17       double complex casinh(double complex z);
18       float complex casinhf(float complex z);
19       long double complex casinhl(long double complex z);

DESCRIPTION

23       These functions shall compute the complex arc  hyperbolic  sine  of  z,
24       with  branch  cuts  outside  the  interval [-i, +i] along the imaginary
25       axis.
26

RETURN VALUE

28       These functions shall return the complex arc hyperbolic sine value,  in
29       the  range  of a strip mathematically unbounded along the real axis and
30       in the interval [-ipi/2, +ipi/2] along the imaginary axis.
