RightToLeft property is used for international applications where the language is written from right to left, such as Hebrew or Arabic.

Are you sure that is what you want, or should you rather set TextAlign property?

Well, that is the RTL behaviour for the .Net TextBox control, comma and dot is interpreted as punctuation unless followed by a number that forms a decimal, in which case the TextBox corrects the placing of that char as you described.

For a numeric input only control you should rather be using the NumericUpDown control. Surprisingly you will see the same behaviour there also, but you can accommodate that by not using RTL and instead right-align that control.
