It crashes because it tries to convert 10**400 to a float and that fails:
>>> 10**400 / 1e200
Traceback (most recent call last):
File "", line 1, in
10**400 / 1e200
OverflowError: int too large to convert to float
But with two ints it succeeds:
>>> 10**400 / 10**200
1e+200
Note that 1e20
That sounds like a lot of extra checks to put on "/" when the error message
is clear and the user could implement their own checks if they are running
into this niche use case and do 10**400 / int(1e200).

This isn’t about the division — it’s about the literal. The “e” notation
makes a float. And floats have fixed precision.
Python could try to be smart and create an integer for e notation

No, it's about the division. Not about the literal. Sorry I was unclear.

Yes, those semi-heroic efforts actually are what inspired my question. A few
days ago I noticed that and was delighted it works.
Use case was the exact calculation of va

If the float argument isn't an integer, you can multiply both sides by a
power of 2 that makes it one (if it's finite, o
