Apfloat for Java

Apfloat is a high performance arbitrary precision arithmetic library. You can perform calculations with a precision of millions of digits with it. It's as simple to use as Java's BigDecimal or BigInteger classes, but performs a lot better with extreme precision numbers (more than a few hundred digits). Also, a full suite of mathematical functions for arbitrary precision numbers are available: all those existing in java.lang.Math and more. Apfloat is distributed under the terms of the GNU Lesser General Public License (version 2.1 or any later version) and comes with NO WARRANTIES.


The apfloat library is also available via Maven.

The source code repository is in GitHub.

Apfloat requires Java 5 or later.

A C++ version is also available.
