Re: Extension: arbitrary precision decimal arithmetic in PHP 7

I wrote a basic benchmark and GMPi appears to be about twice as fast (+ and - ops) but produces a different result. GMPi was also running out of memory when attempting to apply multiply and divide operators. The benchmark only uses + and - now. I used bcmath for the reference value. If there's a bug we can solve here, rather than a fundamental accuracy issue, GMPi looks promising. 😊 See: https://gist.github.com/rtheunissen/973ea1719c02a4204dabfe9dffd78c4b On Sat, Sep 29, 2018, 07:20 Sara Golemon <pollita@php.net> wrote: > On Fri, Sep 28, 2018 at 6:06 PM Rudi Theunissen <rtheunissen@php.net> > wrote: > > I've been working on adding arbitrary precision decimal support as an > > alternative to *bcmath. *I have created an extension based on > *mpdecimal*, > > which is what Python 3's decimal module is also based on.
