python calculations inaccurate

Question

Hi everyone. I've been using the python IDLE and think i may have just discovered an error of some sort. For some reason 2.2 * 3 results in 6.6000000000000005 rather than 6.6. I also tried doing 2.2 + 2.2 + 2.2 and it still resulted in the answer above. I'm curious to see if anyone knows why this is happening. Many thanks.
