Thanks for the PR
It does not render as expected though.

I think you need to use \\(\\times\\)

[mattany]

@qgallouedec Thank you your comment! Sorry about that, this is my first time contributing. Only now I see the message from the bot. I will make corrections now until the rendered docs display correctly.

edit: I made a change now but I don't see it reflected in the docs yet. I guess it takes some time to refresh.

[qgallouedec]

No worry, actually you need me to approve the CI to run so that the doc builds, that's why it just appeared. Let's wait too see if your modification give the expected result
