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] for
n > 0
. When n = 0
, both the min and max bound are 0.
NB: The Num
operators perform wrap-around
on overflow. If you want
saturation on overflow, check out the SaturatingNum
class.

type role Signed nominal ...
as it is not safe to coerce between different width Signed. To change the
width, use the functions in the Resize
class.
