A Python Decimal equivalent isclose method

Question

I'm trying to compare two Decimals in Python with a tolerance of 0.01. When using Math isclose I receive False because of floating point inaccuracy. For example:

d = Decimal('123.12')
d1 = Decimal('123.11')
print(isclose(d,d1,abs_tol=0.01))

Will print out False. I know the reason for this I'm just trying to understand if there is a good way to compare Decimals in Python.

Answer 1

The Decimal class implements many methods with which you can define the comparison easily as follows:

abs(d - d1) <= Decimal('0.01')
