Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

@abhigyan631, you shouldn't modify auto-generated files by hand. Instead, make changes in Module/mathmodule.c and run make clinic. Please take look on https://devguide.python.org/.

BTW, someone already works on this issue: #133907
