Expose minimumFractionDigits for number masking

[Roxanoel]

At the moment, for numbers, we can specify a locale, a maximum number of decimal places, and whether to include the sign. Under the hood, the createFormatter function does take in a param that gets passed to Intl.NumberFormat as the minimumFractionDigits, but it gets programmatically set and not exposed as a field for the number option.
The reason why I noticed this is that I currently have a use case where, independent of locale (and not for a money field), I want the numbers in the field to always have exactly two decimal places, for example 5 should be 5.00, 5.254 should be 5.25, and so on. If the field was exposed, this would be much easier to achieve.

I could expose new setting for minimumFractionDigits. But in this case (when minimumFractionDigits is equal to maximumFractionDigits) you will not be able to delete last digits, like: 5.50| + press backspace = 5.5|0, press backspace again = 5.|00. Is this desirable behavior?
