Arithmetic and comparison operations should be implemented in terms of Haskell's native type classes (`Num`, `Ord`, etc.). However, the user should have control over the size of the posit in question,…

We would like to use the autodiff library with custom arithmetic types, such as posits, valids, unums, Elias, fixed-point, etc. so that autodiff can be used in environments where these types are instr…

Hi,
I'm experimenting with the posit2 implementation in an approximate storage setup (no arithmetic needed) and the error when converting from double/float seems to be way off.
Example:
