Re: Extension: arbitrary precision decimal arithmetic in PHP 7

Hi everyone, I've made some good progress on this project and I would love for someone to review it for me? I want to learn as much as I can to produce something as good as possible. if you are curious to see it in action first, there is a sandbox here: http://php-decimal.io/#sandbox Source is here: https://github.com/php-decimal/extension Thank you. :) Rudi On Sat, Sep 29, 2018 at 10:45 AM Rudi Theunissen <rtheunissen@php.net> wrote: > GNU MPFR looks solid too, significantly faster because it uses base 2 > storage, but may have difficulty converting to decimal.
