| Hi guys, i've been trying to do something which i think might be pretty easy to solve but yet i'm strugling to do it...
Here we go, i have a number for example:
1500700
Thing is i wanted to make something in order to separate that with dots to output something like:
1.500.700 (like a normal number separation)
I was trying to work with string.gsub and string.sub together and alone but i coundnt think on something to solve that...
You guys are my last hope cuz i give up.
Thx in advance. | | Top |

| There is an inbuilt module "commas" that does that:
require "commas"
print (commas ("1500700"))
Result:
You could edit that to change the comma to a dot, or do a string replace, eg.
require "commas"
print ((string.gsub (commas ("1500700"), ",", ".")))
Output:

| The function itself is pretty small:
--[[
Commas in numbers
This function adds commas to big numbers.
For example 123456 becomes "123,456".
--]]
-- ----------------------------------------------------------
function commas (num)
assert (type (num) == "number" or
type (num) == "string")
local result = ""
-- split number into 3 parts, eg. -1234.545e22
-- sign = + or -
-- before = 1234
-- after = .545e22
local sign, before, after =
string.match (tostring (num), "^([%+%-]?)(%d*)(%.?.*)$")
-- pull out batches of 3 digits from the end, put a comma before them
while string.len (before) > 3 do
result = "," .. string.sub (before, -3, -1) .. result
before = string.sub (before, 1, -4) -- remove last 3 digits
end -- while
-- we want the original sign, any left-over digits, the comma part,
-- and the stuff after the decimal point, if any
return sign .. before .. result .. after
end -- function commas
In the middle change the comma to a period if you want a different separator. |
