Another things : using str_replace(",",".",Text.NAOK) didn't work … when EM have it it's . , then need str_replace("."," ",Text.NAOK) to remove the , . No way to see 1.1 …

Issue is here: https://github.com/LimeSurvey/LimeSurvey/commit/49aff574e363cf659e79101b16f59d839427755f

Replacement Action is done even if attr.onlynum = 0

This must be done here : https://github.com/LimeSurvey/LimeSurvey/blob/108cf3522890408673977783c9bce8564fdfe189/assets/scripts/expressions/em_javascript.js#L754
(and maybe for shown too)

Feel free to give me an lss file later so I can make a unit test.

@ollehar : i can do :)

I already have https://bugs.limesurvey.org/view.php?id=15012 and https://bugs.limesurvey.org/view.php?id=14995 to do … but hope i found one day to do it both …

Oups :) think it's the another bug …

This one update API (even if it's a broken API) unsure we can do it for 3.X

Shit … more complex than i think …

The issue is here :
https://github.com/LimeSurvey/LimeSurvey/commit/13e1b2ba8fd54e581e86df6176e8dc7aabf0d263
https://github.com/LimeSurvey/LimeSurvey/commit/b88dd45b0d3cc9454f1a0c23aea67253d7e44a45
etc …

But since there are no related mantis : why this is added is unknow …

OK : EM core to fix …
https://github.com/LimeSurvey/LimeSurvey/blob/2808acfb0099ab1039695970d0a5d76794a15b7e/application/helpers/expressions/em_core_helper.php#L1399

Just … … don't set LEMRadix to ,

Two possible ways to fix this:

1. Stop changing the decimal point to a comma automatically when a value is shown on the same page. Values would then look the same on every page, and anyone who wants the comma can still use fixnum(). The catch: numbers shown on the same page in comma surveys would display with a point instead of a comma, as they already do on later pages.
2. Only ever use the comma for answers to numeric questions, and do it the same way on the same page and on later pages. Text answers would never be changed. This is the nicer result for users, but it is a bigger and riskier change.
