[RESOLVED] Put a comma on last 2 digits while typing in a textbox.

[sapator]

Hey.I have no problem with js or jquery, i have seen some samples and saved them in order for me to try them next week when i would be able to have a Visual Studio enabled computer.So,of course, feel free to post any script.Thanks.
P.S. This is for textboxes that cover doctors general examination values on patience so i suppose it won't need a dot also(p.e. it would be 1000,00 and not 1.000,00) i am just saying that because i haven't been given that exact information and everyone here(including me) are on vacation and i cannot find anyone till the end of the month to clarify this info.So if you have any opinion or experience on this do also advice.But i believe no dot is needed.Thanks again.
P.S.2 Unfortunately i would be going on another island so no free WIFI as off,err,8 hours from now,so i would probably be able to see this on Friday.So take your time.Going to bed...
Edit.Sorry i forgot this.I would like, if possible the comma to appear at the first keyup so when someone writes 1 it would be ,01 when it presses 1 again would be ,11 then again would be 1,11 and again 11,11 etc.
