Class Library for Numbers

Features:

• Rich set of number classes: Integer (unlimited precision), rational, short float, single float, double float, long float (unlimited precision), complex, modular integer, univariate polynomial.
• Elementary, logical, transcendental functions.
• C++ as implementation language brings
  • efficiency,
  • type safety,
  • algebraic syntax.
• Memory efficiency:
  • Small integers and short floats are immediate, not heap allocated.
  • Automatic, non-interruptive garbage collection.
• Speed efficiency:
  • Assembly language kernel for some CPUs,
  • Karatsuba and Schönhage-Strassen multiplication.
• Interoperability:
  • Garbage collection with no burden on the main application,
  • hooks for memory allocation and exceptions.

Requires: C++ compiler g++. The following C++ features are used: classes, member functions, overloading of functions and operators, constructors and destructors, inline, const, multiple inheritance, templates and namespaces. The following C++ features are not used: new, delete, virtual inheritance, exceptions.
