Description

 
Synopsis

Datatypes

newtype Unsigned (n :: Nat) Source #

Arbitrary-width unsigned integer represented by n bits

Given n bits, an Unsigned n number has a range of: [0 .. 2^n-1]

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

>>> maxBound :: Unsigned 3
7
>>> minBound :: Unsigned 3
0
>>> read (show (maxBound :: Unsigned 3)) :: Unsigned 3
7
>>> 1 + 2 :: Unsigned 3
3
>>> 2 + 6 :: Unsigned 3
0
>>> 1 - 3 :: Unsigned 3
6
>>> 2 * 3 :: Unsigned 3
6
>>> 2 * 4 :: Unsigned 3
0
>>> (2 :: Unsigned 3) `mul` (4 :: Unsigned 3) :: Unsigned 6
8
>>> (2 :: Unsigned 3) `add` (6 :: Unsigned 3) :: Unsigned 4
8
>>> satAdd SatSymmetric 2 6 :: Unsigned 3
7
>>> satSub SatSymmetric 2 3 :: Unsigned 3
0

Unsigned has the type role

>>> :i Unsigned
type role Unsigned nominal
...

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

Constructors

U

The constructor, U, and the field, unsafeToNatural, are not synthesizable.
