Formatting numbers or decimals (around comma)

[Joris]

Hi,

I need to print some numbers, but I need to align them in this way (comma always on same position):

 123
   4,5
  26,65
9999,53

So no zero padding, or just replacing by spaces (because in some fonts not all characters have the same size). How do I do this? Is there a library available?

Thanks!

Keep a fix width to the comma, then arrange the leading spaces accordingly. You've to use a fix width, otherwise there is no way to track it.

I'm wonder what's the requirement to align numbers like this.
