doctest options NUMBER and ELLIPSIS seem incompatible

• a detailed description of the bug or problem you are having
• output of pip list from the virtual environment you are using (uv tree used)
• pytest and operating system versions
• minimal example if possible

The NUMBER option supplied by pytest (https://docs.pytest.org/en/stable/how-to/doctest.html#using-doctest-options) seems incompatible with ELLIPSIS from doctest. That is, I can't seem to shorten outputs in non-exception output with ... while having any float outputs respect rounding.

I have a minimal example with virtual environment at https://github.com/wade-cheng/pytest-doctest-bug. Hopefully this makes reproduction easy.

pytest is the only dependency. uv tree shows
