Studying it to learn how to effectively use the bits you need for AP
math would probably take a while. It's also open source (BSD license).
See also which mentions the
object recycling, and the home pages linked from the wikipedia
articles. JScience is apparently built on it. Javolution is also

This may be just what the doctor ordered; thank you.

I especially like these bits:

"Operations on instances of this class are quite fast as information
substantially below the precision level (aka noise) is not
processed/stored. There is no limit on a real precision but precision
degenerates (due to numeric errors) and calculations accelerate as more
and more operations are performed." (Real class API.)

"Transparent Object Recycling For example, our benchmark indicates that
adding immutable LargeInteger is up to 8-10x faster than adding
java.math.BigInteger" (Main page. And with semantically-immutable objects?!)

I can use these under the hood, and maybe even use some of the realtime
stuff throughout the project, which may eventually want or need
distributed capabilities and suchlike. XML externalization as an
alternative to Serializable is also attractive on a number of levels.
