Fix to this problem was figured out and placed to my personal svn (where LNUM can be downloaded).

	svn co svn://

However, I do not intend to make new "distribution" of this, nor carry on the LNUM patch to Lua 5.2.

This is about Lua *with* the lnum patch (And I know, there's still no

This is all beside the point. The whole thing was brought to my
attention by the fact that string.format("%d", 1.00001) was ok while
string.format("%d", 0.999999) would give an error.

This what the sample Lua session in my first post tried to show.

Integers are defined as a subset of real numbers that are *whole* (i.e which can be written without a fractional or decimal component). Numbers between -1.0 < x < 1.0 therefore *cannot* be integers, so unless I've misunderstood,

I already knew that, thanks.

The practical implication however is that -1.0 < x < 1.0 can not be
*cast* to integers. At least not by the %d operator of string.format()

There is no difference between 0 and 0.0 for Lua.
