I am using "n – Digit placeholder. A group of n's can be used to create a numeric section where numbers are entered from right to left. Character must be numeric (0-9) but entry is not required."

Setting a mask input like "nnnn.nnnnnn" makes the control behave like this: when it is entered the cursor is at the left of the decimal point. The digits are entered from right to left. When the limit of digits is hit (the number of the n at the left of the decimal point) or the user pressed the decimal key the cursor moves to the right of the decimal point. Here the digits are entered from left to right.

This I have found to be the natural way of entering real numbers, and the users have no complains.

 HTH,

Emanuel
