I think it may be subjective, 99 % of the time I do want integer

Out of curiosity what are you doing that needs integer division? :)
Still I think that 99% of people expect that when you divide 3 / 2 you get 1.5 (it's like that in every calculators in the world).
3 / 2 == 1 is against the principle of least surprise, but hey I understand that we can't change that anymore in Ruby. :)

Hello!
In my job, I have to do many math operations. And it's kind of a pain because of integer division (3 / 2 == 1). I have to constantly cast integers to floats.
Would it be a good idea to always return a float when you divide two numbers? I mean, 99% of the time you just want that. (The principle of least surprise.)
Python is doing that just right:
~~~ python
3 / 2 == 1.5
3 // 2 == 1
~~~

I don't know if it's too much of a breaking change though? Maybe for Ruby3x3?
Thanks.
