Apache Commons Math

“Commons Math” is undergoing major changes towards the next release (4.0):

• Low-level functionality has been split off to new components, often with many bug-fixes, performance enhancements and improved API:
  • “Commons Numbers” https://commons.apache.org/numbers
  • “Commons RNG” https://commons.apache.org/rng
  • “Commons Geometry” https://commons.apache.org/geometry
  • “Commons Statistics” https://commons.apache.org/statistics
• Functionality still within “Commons Math” is gradually being modularized and refactored.
