lsdelta 0.9.1

Least Significant Digit Delta

LSDelta - Least Significant Digit Delta

lsdelta is a simple little library that provides a single function:

lsdelta(a :str|bytes, b :str|bytes) -> int

This function takes two decimal numbers stored as strings, pads them both to the same length after the decimal point, and then removes the decimal point and subtracts them, giving you the difference in their least significant digits.

>>> from lsdelta import lsdelta
>>> lsdelta("399.999","400")
-1
>>> lsdelta("1035.349", "1035.35")
-1
>>> lsdelta("1035.110", "1035.1")
10

This exists because it's part of a check I sometimes need to do on large datasets, which is why it's implemented in C for speed.
