I'm a Lua newbie. What is the best way to do it?
Very brutal, there must be a better way :)
function self:formatNumber( aNumber, aLocale )
if aNumber ~= nil then
local aString = tostring( math.floor( aNumber ) )
if aString:len() > 3 then
aString = aString:reverse()
aString = aString:gsub( "(%d%d%d)", "%1," )
aString = aString:reverse()
if aString:sub( 1, 1 ) == "," then
aString = aString:sub( 2 )
end
end
return aString
end
return nil
end

Very ugly! Having originally come from South Africa, I shudder when I
see hard-coded separation like this. In SA, we used the comma instead
of the period to display numbers (eg. 10,24 instead of 10.24). I
think
the most common thousand separation was 1 000,24 and I vaguely
remember
seeing 1.000,24 a few times as well (I haven't lived there for some
time). A quick search tells me that Switzerland does something
similar
(and reverts to the common period notation for currency).
It'd be really nice to see a locale-aware method of doing this :-)
