(Not-so) Precise Float Arithmetic in Python [PyOhio 2023]

Published: 17 December 2023
on channel: PyOhio

Talk by Syed Muhammad Dawoud Sheraz Ali at PyOhio 2023:
Just like in other programming languages, floating number arithmetics is not very precise in Python. What makes floats so special and weird that a simple arithmetic operation might not yield the expected result? Why is it so? For instance, what happens when you run the following line on the Python terminal: 0.1+0.1+0.1==0.3? What will be the output? True or False?

This small talk will focus on the underlying behavior of floating arithmetics precision and then discuss a few potential solutions to the problem in Python.
