Why subtraction in float in so large?

Question

I tried subtracting 8.5 from 8.6 , and the answer
was different in 2.x and 3.x versions of Python.
In 3.x the answer came over 0.999999999999864
While in 2.x it was simply 0.1. Why??

Answer 1

Py3 has some limitations with float operations while py2 hadn't. Try referring to this link for description and a solution as well.
