Apache Tuweni provides support for manipulating unsigned integers and base Ethereum currencies.

To get started, install the units library.

With Maven:

{% highlight xml %} org.apache.tuweni units {{site.data.project.latest_release}} {% endhighlight %}

Or using Gradle:

{% highlight groovy %} implementation(“org.apache.tuweni:units:{{site.data.project.latest_release}}”) {% endhighlight %}

The units library revolves mainly around the Uint256, Uint384 and Uint64 interfaces.

This tutorial goes over the main uses of Uint256 - you can apply the same behaviors over to Uint384, Uint64 or Uint32.

It will also touch on Wei and Gas.
