It just confused me that 1%10 was 1.= In my thought process it just didn=E2=80=99t work. 1/10=3D .1 and I just= didn=E2=80=99t see where the remainder of 1 came in. > Ah, yes. When Python 2 -> Python 3 changed the meaning of / the meaning of % got tied instead to //. But if you think about it, with the floating-point result you're describing there, it simply makes no sense to even ask what the remainder is. So, if you're going to use %, use //, and then it all makes sense. ChrisA
