Re: Bug in LNUM patch

[Flemming Madsen <lua@...>]

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

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.

Cheers /Flemming
