Ditto. Thanks Brian.
I agree with your assessment that there is no imperative whatsoever to
do software fixes for something that will go away on its own in a few
weeks. I will just advise editors that {val} may LOOK like it can do

Do you see all those numeric equivalencies in high-precision
scientific notation?
Those types of numbers appear in science articles all over Wikipedia.

Uhm… yeah, division is math; that much is not lost on an R&D engineer.
What I mean is that “in the final analysis” (what {val} *does* for
delimiting numbers), is that no math services are perform

Brion, you can ?action-purge or go to edit mode and hit “Show preview”

Holy crud! You don't use floating point for this! If you need

It appears that the precision setting for PHP may be set
inconsistently across the WMF server pool.
PHP's internal floating point format is the same as a C double giving
~15 digits of precision. By default, current versions of PHP display
14 digits when rendering numbers for output. This is cont
