Lua - Format integer

Question

i\'d like to format a number to look as follows \"1,234\" or \"1,234,432\" or \"123,456,789\", you get the idea. I tried doing this as follows;

function ref         


        

Answer 1

I remember discussing about this in the LÖVE forums ... let me look for it...

Found it!

This will work with positive integers:

function reformatInt(i)
  return tostring(i):reverse():gsub("%d%d%d", "%1,"):reverse():gsub("^,", "")
end
