The patch is not publicly available anywhere, yet. I am using the
INT32_PATCH internally in LuaX future versions, but without this
mention, who would notice? Anyhow, it seems stable to use.
There's actually a couple of more patches in there, each should be
independently on/off settable using following defines:
USE_FLOAT my config for making Lua use float's (affects too many
INT32_PATCH the thing i mentioned, transparent int storage &
can be used either with 'double' or 'float' numbers
ENUM_PATCH an experimental thing for enumarated types / bitwise ops
(similar to int32, but they are actually very different in usage.
this is not transparent, but an extension)
USE_FIXED interesting --very experimental-- patch to use fixed-point
instead of float (preferably, in combination with int32 patch).
This would allow transparent, almost normal Lua behaviour, _without_
using floats (but in the API interface). alternative for total
I'll be glad to send the patched src/ dir contents to anyone wanting it
(did already to you). I am not intending to package it into a dedicated

You might be interested in an int32 patch I did for Lua 5.1 lately. It
is totally transparent to applications, but stores integers as such
internally. Thus, it sort-of brings the best of both worlds, you can
have floats, but you don't need to compromise on integer range, or
performance, if you do.
Sounds interesting. Where is the patch available??
