#15377 closed defect (fixed)

improve documentation for projective normalize_coordinates

For some base rings (such as polynomial rings over a field), the output of the function may seem counter intuitive even though the gcd is correct. The documentation is inadequate to describe this situation.

  • Status changed from new to needs_review

added doumentation and examples. Cleaned up formatting of examples.

comment:2 Changed 5 years ago by tscrim

One thing for line 394; instead of "Beware" (or "Be aware"), I think this would be best formatted as


    The gcd depends on the base ring.

After this it will be a positive review.

Edit - one other thing, could you remove the comma , from line 449.

It fixed the typo and clarified the functionality.

Examples do what they should.

doctest looks good.

I missed this the first go-around but you need to have a proper commit message.

Also why did you choose not to use the .. WARNING:: for the gcd dependency on the base ring?

comment:6 Changed 5 years ago by bhutz

opps. I forgot the commit message. The warning field is a good suggestion and has now been implemented for this patch.

comment:7 Changed 5 years ago by tscrim

Last thing; I noticed (I edited my first comment) is that the comma here

A polynomial ring over a ring, gives the more intuitive result.

should be removed. Thanks!
