memo33 / scala-unsigned   0.2.0

updated to compile with Scala 2.11, 2.12, 2.13

Scala versions: 2.13 2.12 2.11


This is an implementation of unsigned integers for Scala. This is still very much a work in progress.
Much of it was written a while ago as an exercise in learning Scala.

The library provides:

  • UInt
  • ULong
  • UByte
  • UShort

The classes are implemented by boxing Int, Long, Byte, Short, respectively.

Add the following to your sbt build file:

libraryDependencies += "io.github.memo33" %% "scala-unsigned" % "0.2.0"

To use:

scala> import io.github.memo33.passera.unsigned._

scala> (-1).toUInt
res0: passera.unsigned.UInt = 4294967295

scala> res0 + 1
res1: Int = 0


The code was written by Nate Nystrom ([email protected]).


Add support for value classes.

Refactor code to remove redundant ULong code.

More tests.
