Numeric 

LYAHFGG:

Num is a numeric typeclass. Its members have the property of being able to act like numbers.

I could not find Cats’ equivalent for this typeclass, but spire defines Numeric. Cats doesn’t define Bounds either.

So far we’ve seen some of typeclasses that are not defined in Cats. This is not necessarily a bad thing because having a tight core is part of the design goal of Cats.
