When is it safe to compare (==) two floats?

[Radical]

have a look at decimal module from standard library. you are working with money, so always 2 decimal places

I just tried it out and it seems to be doing the exact thing I was afraid float would do.

previousOwing = decimal.Decimal(234.55)
print(previousOwing)

Output:
234.55000000000001136868377216160297393798828125

which is ironic, because float seems to work perfectly:

previousOwing = float(234.55)
print(previousOwing)

Output:
234.55
