Re: lua_number2int in bitwise operators Lua 5.2 work 3 (MSVC)

Double 0xFF000000 is too big to be represented by a signed integer.

You should get value from Lua stack as double then cast it to unsigned integer.�

On MSVC compiler this construction

#define lua_number2int(i,n) �__asm {__asm fld n � __asm fistp i}

Example:

bit.band(0xFF000000, 0x00FFFFFF)

while debug after getting from stack, the first value is 0x80000000, second 0xFFFFFF
