That would be an odd back-step since Python 3 generalized the built-in:
>>> class Test:
... def __round__(self, ndigits=None):
... return 1
...
>>> round(Test())
1
Also, float, Decimal, and Fraction in Python 3 return an int when the
ndigits argument is omitted. For example, float rounds using the math
lib's round function, then rounds that to even, and returns
PyLong_FromDouble. Is the discussion just about removing the ndigits
aspect but keeping the round-to-int aspect?
I don't have figures (ouch :) but some people appear to support complete
deprecation, some leaving the status quo and some removing the ndigits
aspect as you have asked. Also remember that the idea is only being
floated (double ouch:) on Python ideas so anything could happen. Don't
watch this space!!!
