Re: How does Lua round non-integer numbers in standard library ?

[Marco Mastropaolo <marco@...>]

Thank you very much for your answers!

Given the changes in Lua 5.3 and the intentional non-specification in Lua 5.2, I'll just won't care about the rounding method.

Thanks again
Marco

Well, it kind of does it, in a rather obscure way: In the documentation
of 'lua_tointegerx', which is what libraries use to do the conversion :-)

  lua_tointegerx
  ...
  If the number is not an integer, it is truncated in some non-specified
  way.

(But you got the point correctly; the idea is not to say much about it...)
