Conversion from latex to html

edit

Please, stop to systematically convert formulas from latex to html. This is strongly discouraged by MOS:FORMULA, as being controversial. In fact there is a consensus among mathematics editor to uses latex in displayed formulas (except, maybe, for very simple formulas). For inline formulas, there is no clear consensus, as, presently, inline latex formulas are not perfectly aligned horizontally. On the other hand, there is a strong consensus, when using html rendering, to use {{math}} template, since, otherwise, the rendering of the variable names is so different from that of latex that this may be confusing for the reader. So, please, stop such edits, unless there are strong reasons. In this case, you must discuss them on the talk page, or, at least make them explicit in the edit summary.

What I edited should be very simple formulas. Do you think it is good to use {{math}} consistently for those edits I made? --Shiyu Ji (talk) 16:11, 1 September 2018 (UTC)Reply

If you have used {{math}}, I would not have reverted all your edits, although, again, this is strongly discouraged. However, some change the notation (such as changing   into C), and would be reverted in any case. D.Lazard (talk) 16:34, 1 September 2018 (UTC)Reply
I will leave them unchanged if no confusion. But the problem of inconsistency exists. For example see Talk:Injective_object. --Shiyu Ji (talk) 16:38, 1 September 2018 (UTC)Reply

April 2020

  Hello. Regarding the recent revert you made: you may already know about them, but you might find Wikipedia:Template messages/User talk namespace useful. After a revert, these can be placed on the user's talk page to let them know you considered their edit inappropriate, and also direct new users towards the sandbox. They can also be used to give a stern warning to a vandal when they've been previously warned. Thanks for helping revert vandalism, but it would be helpful to warn users whose edits you've reverted. You can do this easily with Twinkle by by pressing "Warn" under the TW tab at the top left of a User_talk page. userdude 21:52, 1 April 2020 (UTC)Reply

Thank you. I think I have learned how to use the Warn button now. --Shiyu Ji (talk) 22:12, 1 April 2020 (UTC)Reply
