## Uses of Interface
cern.colt.function.IntFunction

- Packages that use IntFunction
  Package | Description
  --- | ---
  cern.jet.math | Tools for basic and advanced mathematics: Arithmetics and Algebra, Polynomials and Chebyshev series, Bessel and Airy functions, Function Objects for generic function evaluation, etc.
  cern.jet.random | Large variety of probability distributions featuring high performance generation of random numbers, CDF's and PDF's.
