Why are calculations in Python wrong? (SOLVED)

Question

When I type 3.3- 3, the answer is not 0.3 but 0.299 something. Same with 2.2-2 etc. What exactly is wrong? Why is this happening?

Answer 1

This is because of famous floating point error (occurs in almost all languages that support floating point arithmetic)
