Issues with .99999999999...
Here is a result that I found surprising and I don't understand completely what corercian is causing it.
sage: int(.9999999999999999) 0 sage: int(.99999999999999999) 1 sage: int(0.99999999999999999) 0 sage: int(0.9999999999999999) 0 sage: int(0.999999999999999999999999999999999) 0
What is going on?
