Comaparing Float Values of Dictionary Against A Float Value & Pick Matching Key

[scidam]

It is worth noting that floats comparison needs additional care when performed.

Look at the following example:

1.3 / 3.9 == 13 / 39

Output:
False

This is due to the finite accuracy of representation float numbers in computer memory.
As of Python 3.5 (PEP-485), you can do such a comparison using math.isclose function.

import math
math.isclose(1.3 / 3.9, 13 / 39)

Output:
True
