Why does adding certain numbers such as 3.6 and 3.2 give several "0"s as an output Python

Question

Has anyone come across the problem where you add certain numbers such as 3.2 + 3.6 in python 3 you get an output like "6.800000000000001". This has occurred when I was using Python 3.8. One other set of numbers I added was 2.6 + 2.2 which gave the same result. Does anyone know why this happens, and only on these few numbers?

print (3.6 + 3.2)
print (2.6 + 2.2)

@Energya Then why does it do this with these numbers when something like 4.3 + 4.4 gives 8.7 — NFuze, Jun 26 '20 at 23:06

You'll find some good info/explanations in Python docs themselves about floating point arithmetic in computers.
