History

Non-expression template operators further optimised with rvalue reference support.
Many functions made constexp.
Differentiate between explicit and implicit conversions in the number constructor.
Removed "mp_" prefix from types.
Allowed mixed precision arithmetic.
Changed ExpressionTemplates parameter to class number to use enumerated values rather than true/false.
Changed ExpressionTemplate parameter default value to use a traits class so that the default value depends on the backend used.
Added support for fused-multiply-add/subtract with GMP support.
Tweaked expression template unpacking to use fewer temporaries when the LHS also appears in the RHS.
Refactored cpp_int_backend based on review comments with new template parameter structure.
Added additional template parameter to mpfr_float_backend to allow stack-based allocation.
Added section on mixed precision arithmetic, and added support for operations yielding a higher precision result than either of the arguments.
Added overloads of integer-specific functions for built in integer types.

2011-2012, John Maddock adds an expression template enabled front end to Christopher's code, and adds support for other backends.
2011, Christopher Kormanyos publishes the decimal floating point code under the Boost Software Licence. The code is published as: "Algorithm 910: A Portable C++ Multiple-Precision System for Special-Function Calculations", in ACM TOMS, {VOL 37, ISSUE 4, (February 2011)} (C) ACM, 2011.
2002-2011, Christopher Kormanyos develops the all C++ decimal arithmetic floating point code.
