So as far as I understand, see my other mail: the integrated intdiv0
function (earlier known as intdiv) works fine, both on Linux and macOS.

Due to some magic, the current indiv extension operates on a higher
precision than expected -- but only on Linux. Adding PREC=400 on macOS
doesn't make any difference.

You could pass by and fetch one ;-)
