Precise floating point math #5

Closed dozed-dev closed 1 year ago

dozed-dev commented 3 years ago

Binary floating point math is imprecise when dealing with decimal numbers, for example 1.1 0.5 - is calculated as 0.6000000000000001. This could be solved if the numbers are represented as rational internally, because rational numbers use integer math.

This library, for example, provides computations on rational numbers.

I hope this won't be too much trouble to implement, and thank you for making this app :)

Thanks for sharing that library--I'll take a look at how hard it will be to implement this.

Gave this a try and it was a simple change, so this fix will be included in the next release. I'll probably be able to have it out on the Google Play version next week, but given the slow and unpredictable pace of F-Droid's build + release process, it may be a few weeks before it lands there.

So this was already solved wan't it?
