Hi! I was experimenting with floor division in Sage using the int and float
types of Python and Integeger and RealNumber types of Sage to understand
the differences. I've found that the floor division operator (//) in Sage
does not support real numbers. Is there a reason for this? (I ask just for
curiosity)
int(5)//float(2.0), int(5)//float(-2.0)
(2.0, -3.0)
ZZ(5)//RR(2.0), ZZ(5)//RR(-2.0)
Error in lines 1-1
