Snohetta

Faster Scala BigInteger.

Developed during my personal research with projects that required faster math libraries but that used Scala. In particular computing extremely large numbers.

Usage

See tests on how to use this code.

Building and Testing

git clone git@github.com:JasonGiedymin/Snohetta.git
sbt compile
sbt test
