  NumberTransformer	Subclasses implementing this interface can transform Objects to doubles.
  PivotingStrategyInterface	A strategy to pick a pivoting index of an array for doing partitioning.

• Class Summary 

  Class	Description
  ArithmeticUtils	Some useful, arithmetics related, additions to the built-in functions in Math.
  BigReal	Arbitrary precision decimal number.
  BigRealField	Representation of real numbers with arbitrary precision field.
  CentralPivotingStrategy	A mid point strategy based on the average of begin and end indices.
  Combinations	Utility to create combinations (n, k) of k elements in a set of n elements.
  CombinatoricsUtils	Combinatorial utilities.
  CompositeFormat	Base class for formatters of composite objects (complex numbers, vectors ...).
  ContinuedFraction	Provides a generic means to evaluate continued fractions.
  Decimal64	This class wraps a double value in an object.
  Decimal64Field	The field of double precision floating-point numbers.
  DefaultTransformer	A Default NumberTransformer for java.lang.Numbers and Numeric Strings.
  FastMath	Faster, more accurate, portable alternative to Math and StrictMath for large scale computation.
  Incrementor	Deprecated Use IntegerSequence.Incrementor instead.
  IntegerSequence	Provides a sequence of integers.
  IntegerSequence.Incrementor	Utility that increments a counter until a maximum is reached, at which point, the instance will by default throw a MaxCountExceededException.
  IntegerSequence.Range	Generates a sequence of integers.
  IterationEvent	The root class from which all events occurring while running an IterationManager should be derived.
  IterationManager	This abstract class provides a general framework for managing iterative algorithms.
  KthSelector	A Simple Kth selector implementation to pick up the Kth ordered element from a work array containing the input numbers.
  MathArrays	Arrays utilities.
  MathUtils	Miscellaneous utility functions.
  MedianOf3PivotingStrategy	Classic median of 3 strategy given begin and end indices.
  MultidimensionalCounter	Converter between unidimensional storage structure and multidimensional conceptual structure.
  OpenIntToDoubleHashMap	Open addressed map from int to double.
  OpenIntToFieldHashMap<T extends FieldElement<T>>	Open addressed map from int to FieldElement.
  Pair<K,V>	Generic pair.
  Precision	Utilities for comparing numbers.
  RandomPivotingStrategy	A strategy of selecting random index between begin and end indices.
  ResizableDoubleArray	A variable length DoubleArray implementation that automatically handles expanding and contracting its internal storage array as elements are added and removed.
  TransformerMap	This TansformerMap automates the transformation of mixed object types.

• Enum Summary 

  Enum	Description
  MathArrays.OrderDirection	Specification of ordering direction.
