HTML is text and nothing but text. The JSF converters are simple pairs of methods designed to translate objects from their server-internal (binary) forms to text and back again.
Number formatting applies only to text representation of numbers. There is no such thing as a java.lang.Integer(10,005), because the digit separator (comma) isn't an attribute of Integers, it's a way of formatting the Integer for display purposes, and that process is not part of actual Integer itself, it's a transformation that uses an Integer as input.
Reading a number with digit separators and converting it to an Integer is going the other direction, and the opposite of "format" is "parse". The Java NumberFormat converters that come as part of the basic JVM package handle both formatting and parsing.

One of the most odious afflictions that Business has inflicted on the modern English language is "pro-active". Most of the time it's simply redundantly used in place of the simple old word "active". And a good deal of the rest of the time it means "You're not overworked enough yet, so go out and find more!"
