I'm not going to report the problem yet, I'm a rookie, and this is my first time to report the problem

Closing as this is a Cython bug and not a CPython one. I also suspect this is triggering integer division and therefore is actually not a bug at all.

However, in the source code, the source code runs normally, and when compiled and encapsulated with Cython, an exception occurs，Trigger divisible 'a = 5 // 6'，this possibility does not exist.I checked it out :'a = 1,b = 5 / 6 + a'，return :'a = 0'

Please report this to the Cython bug tracker: https://github.com/cython/cython/issues/

When you do that, you'll want to show the actual code you're having a problem with. You're using both "//" and "/" here. As Pablo said, you're probably having a problem with integer division ("//").

Thank you for your patient answer, but I still don't understand.I have uploaded my file (*.py).I hope you can solve my problem. I want 'a=5/6' to return 'a= 0.833333333333333...... 'after compilation.
