Library for polynomial calculus in Java?

Question

Are there any (preferably open source) library for Java that allows one to do calculus with polynomial e.g. addition, multiplying, dividing by constans etc. ? Also if it would be capable to interpolate several 2D points in a polynomial with Lagrange polynomial interpolation, it will be a plus.

I always check for Apache contributions first ... have you seen this?: https://commons.apache.org/proper/commons-math/javadocs/api-3.0/overview-summary.html

This looks very intriguing, although it may not be everything you want: https://github.com/danielleontiev/polynom
