Ability to format numbers with commas

Ability to format numbers with commas

1. When using the "integer" option for adding a field, is there any way to make it autoformat to add commas?

1a. example: if you type "1000000" and hit save, it would display "1,000,000"

2. What about the ability to add decimals to an integer?

2a. example: if you type "1000000.25" it would display "1,000,000.25"

This is similar to the currency system that is already in place.
