No..

I want to format the number that a certain user writes in a textbox. For example:

If the number in the textbox, wrote by the user is: 150
then the program have to format it to have 2 decimals.
Once a button is pressed.. the value must become: 150,00

If it was: 150,3 it must become: 150,30
If it was: 150,45 it stays like that because it already have 2 decimals.

and if the number is too big, like: 145700,4
the number must have 2 decimal cases (as before) and a point (.) It must become: 145.700,40

I know this is a lot of work.. but if someone could help me.. I would be very happy.
