string.gsub - cuestion

[Cocodrilo]

I use :

local money = getPlayerMoney(getLocalPlayer()) 
string.gsub(money,"^(-?%d+)(%d%d%d)", '%1,%2') 

When money is

1 000 = 1,000

10 000 = 10,000

100 000 = 100,000

etc.

But When money is 1 000 000 returns 1000,000. How i get 1,000,000 ? *without modifying the previous examples

Use comma_value function for that.

local money = getPlayerMoney(getLocalPlayer()) 
local formattedMoney = comma_value(money) 
  
-- from [url=http://lua-users.org/wiki/FormattingNumbers]http://lua-users.org/wiki/FormattingNumbers[/url] 
function comma_value(amount) 
  local formatted = amount 
  while true do   
    formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2') 
    if (k==0) then 
      break 
    end 
  end 
  return formatted 
end

Alternate version with no loops.

function commaNumber(n) 
    local left, num, right = string.match(n, "^([^%d]*%d)(%d*)(.-)$") 
    return left..(num:reverse():gsub("(%d%d%d)", "%1,"):reverse())..right 
end
