Re: Can lua 5.2 support int64?

Thanks a lot.
My compiler is vs2008(vc9) I have try to define LUA_INTEGER long double,
and also have the problem:


Lua 5.2.0 (alpha)  Copyright (C) 1994-2010 Lua.org, PUC-Rio
> a, b = 9223372036854775807, -9223372036854775808
> print(a,b)
9.2233720368548e+018    -9.2233720368548e+018
>


Can somebody help me ?
