Also, with a mask = "##.##" or "99.99", it force me to enter 2 digits before the point before being able to enter the decimal part.

What I need, is to be able to enter "1.23" ("1", ".", "2", "3") directly, not " 1.23" (space, "1", "2", "3"). In other word, if the user press the decimal point ("."), the cursor move to the decimal part and the integer part is padded to the left with blank.

Ex. 1:
1-.-2-3 become "1.23", not "1 .23" or "12.3"

Ex. 2:
1-2-3-4 become "12.34"

The decimal point is optional for the user. The user enter it only if he want to jump to the decimal part.

TIA
