Description Derk-Jan Hartman 2012-09-07 18:02:41 UTC

Mwlib seems to be unable to handle the following:

{{#expr:(1E5round0)E5}}

Comment 1 Derk-Jan Hartman 2012-09-07 18:05:37 UTC

Filed upstream (i think it's number is 3546)

Comment 2 Ruslan 2012-09-09 11:07:17 UTC

In fact an error appears in any expression that contains parentheses () before E operator: {{#expr:(1)E5}}. It can be fixed by inserting multiplication:  {{#expr:(1)*1E5}}.

Comment 3 Ralf Schmitt 2012-09-21 20:14:12 UTC

really guys, e shouldn't be an operator. this is just braindamaged.

thinks like "e e e" and "1e2e5" should raise a syntax error. the current mediawiki version evaluates them happily. wtf!

I've implemented that in mwlib.

I'm setting the component to ParserFunctions, since this issue should really be fixed there.

please read https://en.wikipedia.org/wiki/Scientific_notation

Pinging Umherirrender in case you want to make an attempt at fixing this issue in ParserFunctions.
