Datatypes

newtype Signed (n :: Nat) Source #

Arbitrary-width signed integer represented by n bits, including the sign bit.

Uses standard 2-complements representation. Meaning that, given n bits, a Signed n number has a range of: [-(2^(n-1)) .. 2^(n-1)-1]

NB: The Num operators perform wrap-around on overflow. If you want saturation on overflow, check out the SaturatingNum class.
