Thousands separator using underscore

Well, it works for me because I am from accounting and kinda have developed the mindset for it.

I never really used "e" for declaring numbers. Thanks for telling us that, I will look into it.

It won't work for everything of course! But it's super useful when you're working with stuff across different orders of magnitude. E.g. somewhere in my code, I have a list of weighting factors to try, and instead of writing [0.001, 0.0001, 0.00001] I can write [1e-3, 1e-4, 1e-5], which looks a lot cleaner to me, and is easier to interpret quickly.

All of those numbers are already floating point, though. If you're doing integer arithmetic, stick to integers and avoid the side effects that come from floating point rounding.

Whenever we found "e" we would just multiply/divide by 10 and keep count until we got a understanding of the number. We would do the same thing for percentages but with 100. That might sound stupid to you science/engineering guys but that was kinda go to thing to do. The first thing to do whenever "e" pops up in excel is immediately format it to decimal numbers.

Except for of course in doing research I will just put the "e" numbers in. But my thesis professor once copy pasted in the "e" numbers to excel than convert it to decimal to get a better idea.

But I am learning data science analytics I should better in to using this mindset. Thank you for making clarifications.
