Screenshot.cs - unfinished code?

I stumbled across the screenshot.cs stuff and the first two functions seem to finished. I'll mark the lines I mean bold - the string is always set to "0" + %number. I guess it should be some kind of fill mechanism to have leading zeros. But now it's always only 1 zero. Is that intended?

common/client/screenshot.cs

function formatImageNumber(%number)
{
   if(%number < 10)
      [b]%number = "0" @ %number;[/b]
   if(%number < 100)
      [b]%number = "0" @ %number;[/b]
   if(%number < 1000)
      [b]%number = "0" @ %number;[/b]
   if(%number < 10000)
      [b]%number = "0" @ %number;[/b]
   return %number;
}

function formatSessionNumber(%number)
{
   if(%number < 10)
      [b]%number = "0" @ %number;[/b]
   if(%number < 100)
      [b]%number = "0" @ %number;[/b]
   return %number;
}
