[issue24270] PEP 485 (math.isclose) implementation

[Tal Einat]

Tal Einat added the comment:

@Stefan K.: I tend to agree, but still think that's a separate issue. math.isclose() certainly shouldn't be checking the type of its arguments.


While we're on the subject, though, trying to convert a very large int to float fails with an OverflowError. Perhaps Decimal should do the same?

>>> float(10**999)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: int too large to convert to float

>>> math.isclose(10**999, 10**400000)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: int too large to convert to float
