Squants
The Scala API for Quantities, Units of Measure and Dimensional Analysis
Overview
Squants is a framework of data types and a domain specific language (DSL) for representing Quantities, their Units of Measure, and their Dimensional relationships. The API supports typesafe dimensional analysis, improved domain models and more. All types are immutable and threadsafe.
