Mate, you should pass string values in Decimal constructor, like Decimal("0.1") + Decimal("0.2"). It works perfect without double conversion from/to float

i have proble in vidstrem lib , on Audiosender class,, when i want I want a way to make the function stop, because when I stop it in a way: sender2 = AudioSender(awayIP, awayPORT).stop_stream() Several problems occur, can you help please..

Could somebody please explains the difference between deciding the precision of the Decimal vs rounding ? In case we want a precision of second decimal place (Ex x.xx where x is a number between 0 and 9)

The inaccuracy of normal floating point numbers, with rounding, could make it so that the number gets rounded the wrong way in some cases. You might think it'll be fine in 99% of cases, but considering most code doesn't run only once but rather runs over and over and over, eventually you will run into issues of numbers getting rounded the wrong way and you either won't notice it at all or until it actually starts causing issues. Which, there are a lot of ways those tiny inaccuracies can cause issues as shown in the video.

num7 package is easier to use and with better precision.

Decimal arithmetic isn’t about “accurate” floats, since it is just as inaccurate as regular binary floats, only in different places. It’s just that the rounding errors are less surprising, because they come out of the same base-10 arithmetic we all learned to do by hand. That’s all. Python’s decimal module allows you to specify very large precision, but that’s quite separate from the issue of whether base-10 or base-2 arithmetic is better. For example, neither of them can represent 1/3 accurately -- if you want that, you need the fractions module.

Why are you asking on a python decimal video?

If there is a M2 slot on the board (for the existing ssd or even just a wifi board you should be able to put a ssd inside - if not the best you can do is a fast sd-card or external drive.

The other video that you were mentioning where you explained why 0.1 + 0.2 = 0.3000004 === You should put the link of that video in your description. Atleast in comments??? @NeuralNine
Why is 0.1 + 0.2 Not 0.3 in Python?
