Store it internally as Decimal

[sindresorhus]

It would allow us to store bigger values with more precision. We would also accept a Decimal and add arithmetics overloads for it.

I don't intend to do this yet if at all as Decimal has and still is very buggy:

• JSONDecoder Decimal precision error
• Decimal initialized with Double loses precision

Even though I don't plan to do this yet, I'm still looking for feedback on whether it makes sense at all.

Closing as this is not feasible. In addition to the above points:

• There's no literal syntax for Decimal. It needs to be passed as a string, which makes using % impossible.
• Even if we store Decimal internally, the main use-case is to pass it to methods that needs a Double-like type, so we would lose precision every time it's used in practice anyway.
