Free and open source precision math Java framework JQuantity is a framework of classes for developing mathematical and scientific calculations which are either precise or have known precision. The classes in the framework are based on the java.math.BigInteger class and thus are not limited in size or precision. Rational numbers are stored as ratios, transcendental numbers are represented in their own domain, typically precisely. Numbers can be associated with units, numbers can be complex and can be managed as matrices. Numbers can be presented in a structured text class, which can in turn be rendered as a string of characters. JQuantity has been and continues to be developed for the educational, mathematical and scientific community.

Requirements: · Java What's New in This Release: · Several improvements and bug fixes, especially in the units subsystem (which has been moved into its own package). · A number of fundamental physical constants have been added. · Most non-basic units definitions are now in a separate config file (units.ini). · Fixed some problems in presentation of Rational numbers. · Added a new interface for the creation of lookup tables required by application. · New "Test" class better demonstrates how applications should use framework.
