Description (last modified by mjo)

Some of these were fixed in #10772, but a few remain. Find/grep show,

  • ./rings/padics/padic_capped_relative_element.pyx
  • ./rings/padics/padic_fixed_mod_element.pyx
  • ./rings/padics/padic_ZZ_pX_CR_element.pyx
  • ./rings/padics/padic_ZZ_pX_FM_element.pyx

Unless any of these are special (for whatever reason), we should return 1 instead from the appropriate ring.

See also: #13894, #13895, #13897, #13941.

Just a general statement on the documentation in these patches. I'd prefer to see the 0^0 formatted either in latex `0^0` (which would display as 00) or as a code literal ``0^0``.

Thanks,
Travis

comment:9 Changed 8 years ago by mjo

I finally added double backticks to the other patches. While those functions aren't in the reference manual, they should and hopefully someday will be.

comment:10 Changed 8 years ago by tscrim

Thank you. It suppose to make the docreader (which may only really be me) understand that it is suppose to be code/input.

Also, for the remaining ones in the padics, could you just put them all in one patch (possibly on this ticket)?

Thanks,
Travis

  • Status changed from new to needs_review

Patch is up. I had split them initially to make it easier for (potentially) multiple reviewers. Thanks for taking a look at all of them.

I've removed ntl_lzz_p.pyx from the list per #13940. This patch should take care of the remaining four.

Replying to mjo:

I've removed ntl_lzz_p.pyx from the list per #13940. This patch should take care of the remaining four.

Does this depend on #13940 anymore?

comment:16 Changed 8 years ago by mjo

  • Dependencies #13894, #13895, #13897, #13940, #13941 deleted
  • Description modified (diff)

No, good catch. I've removed all of the dependencies; no need to confuse things. This patch can be merged without any of those. If an archaeologist is curious, he can check the description diff.
