Why 1.2*3 returns 3.5999999999999996 and not 3.6 in python 3.7 ? For other cases it gives correct value but why in this question it doesn't return 3.6

In Python, you can use [`decimal`](https://docs.python.org/3/library/decimal.html) if this behaviour is a problem for you. – Amadan Apr 11 '22 at 03:43
FP can represent many values. 3.6 is not in that set. The closest value it can represent is about 3.5999999999999996.... – chux - Reinstate Monica Apr 11 '22 at 04:09
