Benoy Antony commented on HDFS-7483:
------------------------------------
To add on, I had tried the approach while working on the patch. _math_ is a
helper whereas fmt_percentage is a filter. We cannot do something like
"helper | filter" . Some helpers support a "filters" attribute. But math helper
does not support "filters" attribute. So I could not reuse math helper and
fmt_percentage filter. That's why I wrote a a new percentage helper.
