Comparing new and old code I found these differences:

1) While current version just cuts to two decimals, number_format()
rounds. So 0.015 will be 0.01 in old and 0.02 in new version.

2) Space as thousand separator isn't recognized anymore: "1 222.33" was
"1222.33" before and now leads to "1.00".

3) A comma or dot as thousand separator leads to unexpected results in
both versions: The str_replace only removes space from $value, and
number_format() doesn't recognize it at all. We get two different wrong
values ;)

At the moment I only tested the TCE processing and disabled js parsing
in my tests.

I am unsure if we can use this version, maybe I am a bit too nitpicking,
but I think it is at least a different behavior and can't go to 4.2.
