This is one of the more challenging questions on ScalaZONE. What's the answer? https://scala.zone/courses/scala-beginner/concepts/floatingpoint …pic.twitter.com/bMBBKPqyKw

Some Mantissa-fu needed there. Never my strong suit, but unless there’s a range check that returns a different type, I don’t see what this has to do with Scala
It's more general than Scala, but it's useful for any Scala developer. But why do you want a different type?

I don’t, just wondering what I’m missing. I would also argue about the “useful for any...” statement; if numeric analysis (Spark et al) is the focus, sure. Otherwise this is way too deep for most - akin to requiring bitwise arithmetic of a full stack dev
-
I think the main point is "don't expect floating-point numbers to work like real numbers". It's still a tough question, though.

Add the small numbers to other small numbers first is best for the accuracy. I would expect a visible difference.

Yes, the difference is about 2.7e-12 for doubles, or 1.3 if we use floats!
