NAME
cacosh, cacoshf, cacoshl - complex arc hyperbolic cosine functions
SYNOPSIS
cc [ flag... ] file... -lm [ library... ] #include <complex.h> double complex cacosh(double complex z); float complex cacoshf(float complex z); long double complex cacoshl(long double complex z);
DESCRIPTION
These functions compute the complex arc hyperbolic cosine of z, with a branch cut at values less than 1 along the real axis.
RETURN VALUES
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 [ -i, +i ] along the imaginary axis.
ERRORS
No errors are defined.
