Float DataType in Python

Question

Why
>>> (1.1 + 2.2) == 3.3
False
>>> (1.1 +1.2)==2.3
True

I know 0.1 corresponds to 0.000110011001100110011... in binary thus first one is False but this should also happen with second.

Answer 1

Because the actual answer of the first one is:

3.3000000000000003
NOT:
3.3

Unlike the second one
It's actually:
2.3
