But I care below with luajit 2b8 head

Lua 5.1.4 Support  64bits int, but luajit support only 32bits.

I hope not to require other math libs support 64bits integer.

Support for hexadecimal floating-point numbers is a C99 feature.
MSVC is not C99-compliant, please complain to Microsoft.

Note that you're getting a wrong result with plain Lua. Would you
rather silently get a wrong result or a proper error message?
