[ruby-core:88022] [Ruby trunk Feature#14924] // floor division operator

Issue #14924 has been updated by deneb (S辿bastien Durand).


Oh too bad regular expressions use the same synthax. :(

Yes, it's a big breaking change to always return a float when dividing two integers. I understand that Matz doesn't want that.

So you can close this ticket then.

Thanks guys!

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
~~~

http://python-reference.readthedocs.io/en/latest/docs/operators/floor_division.html

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

Thanks.
