title: "commons-math"-like Implementation for BigDecimal / BigInteger
body: <p>I'm looking for suggestions regarding a third-party library to use for statistical analysis on numbers encoded in BigDecimal / BigInteger.</p>
  
  <p>Apache commons-math contains all the ideal functionality (it's DescriptiveStatistics and SummaryStatistics)... but it's using doubles instead of the BigXXX implementations.</p>
  
  <p>I am required to use the BigXXX implementations due to regulatory requirements on my software's precision. But I'm very keen not to roll-my-own implementation of the fundamental statistics that I will require.</p>
  
  <p>For example, it’d be easy enough to write my own median algorithm – but it seems counterintuitive to pick-up high-precision data types, and then use my own immature (therefore, probably bug-ridden) methods to perform statistics on them.</p>
