CACOSH(3M) Mathematical Library Functions CACOSH(3M)

cacosh, cacoshf, cacoshl - complex arc hyperbolic cosine functions

#include <complex.h>
double complex cacosh(double complex z);

float complex cacoshf(float complex z);

long double complex cacoshl(long double complex z);

These functions compute the complex arc hyperbolic cosine of z, with a branch cut at values less than 1 along the real axis.

These functions return the complex arc hyperbolic cosine value, in the range of a half-strip of non-negative values along the real axis and in the interval [ -ipi, +ipi ] along the imaginary axis.

No errors are defined.
