Encoding/Decoding on Windows 64Bit machine

[NicolasDucom]

Hi Jens,
I'm currently trying out Optimus on a Windows 64Bit Machine with Laravel 5.1.20 and am having a bit of trouble decoding my numbers :

PRIME=1580030173
INVERSE=59260789
RANDOM=1163945558

1=>458047115=>0
2=>2033899500=>0
3=>1609067713=>4
4=>1037370658=>0
5=>327342599=>0
6=>1886417784=>8
7=>1448937565=>8
8=>873111742=>0
9=>184056211=>16
10=>1755651828=>8
11=>1318237993=>12
12=>792742922=>16
13=>221111663=>16
14=>1662696000=>16
15=>1103647397=>15
16=>666233734=>16

Could I be missing something ?
Thanks for the help ;)

Are you using 64-bit PHP? According to their site, those builds are experimental for anything older than PHP 7. That might be the reason.

I'm seeing correct results in 64-bit Windows with 32-bit PHP 5.6 and the GMP extension.
