>>> print(3.5 % 0.1)0.1>>> print(3.5 % 0.1 == 0.1)FalseIn actuality, on most systems, 3.5 % 0.1 is 0.099999999999999811. But, on some versions of Python, str(0.099999999999999811) is 0.1:
>>> 3.5 % 0.10.099999999999999811>>> repr(3.5 % 0.1)'0.099999999999999811'>>> str(3.5 % 0.1)'0.1'Now, you're probably wondering why 3.5 % 0.1 is 0.099999999999999811 instead of 0.0. That's because of the usual floating point rounding issues. If you haven't read What Every Computer Scient...
