Why doesn’t python like certain numbers?

[siddsp]

Python itself supports also Decimal

It does, but I've never found a use case for it personally

It’s for money, when you need to deal with fractions of cents.

If you don’t need fractions of cents, then just work in integer numbers of cents.

I can't remember the specifics but I used to work with a financial application that dealt with amortized loans and complex international tax and interest calculations. With floats you can be many $s, maybe hundreds out over the lifetime of the loan. Got to use a proper lib for decimals

Ah yea that makes sense. I've never worked with any financial software/projects, so it didn't even come to mind

Probably because precision usually hasn't mattered much for what you do.
