Disabling the Use of Comma on Currency Fields

As default Comma is set for Thousands and Dot for decimal Separators.

Removing comma from typing in currency fields is a good pratice to avoid system errors.

Same should happens with dot is separators are the opposite.

Example:

When open register you need to type the field as Cash Amount, it always happen to type comma instead of dot by mistake due keys are close in keyboard. So, register opening cash amout gets totally wrong.

If comma is disable on those fields this would never happen. And it is a good pratice in most of systems to avoid mistakes like that.
