Removed from HEAD, will be on math_toolkit branch in future.
Added library for a radix-specific arbitrary-length unsigned integer type (class template)
Added single-digit assignment member function
Added single-digit modulo-only member function; added member functions to detect even/odd; did minor code clean up
Added digit-altering (member) functions; changed speculative full-precision member function prototypes
Refined pre-condition
Added missing paranoia check
Added single-precision absolute-difference member functions; prototyped mixed- and full-precision variants; re-grouped some tests
Added shifted-product variants of the add/subtract(absolutely) single-product member functions; begin to unify the deque iterator/reference typedef's; slightly revamp the numeric-limits traits specialization
Extensively used class-local aliases for the aliases within the deque type; added Doxygen block markers
Added addition, subtraction, and absolute-subtraction member functions for full-length operands
Fixed comment
Added fused-multiply & addition/(absolute-)subtraction member functions for mixed-sized (one full-length, one single-digit, one shift factor) operands
Added fused-multiply & addition/(absolute-)subtraction member functions for full-length operands; added multiplication operators (implemented with the full-length fused-multiply/add member function); fixed description error in 'subtract_mixed_product_absolutely'
Added quotient & remainder integer-division member function; added division and modulus operators (implemented with the integer-division member function)
Added testing of generic numeric conversions with unbounded destination types
Added member functions to multiply and integer-divide by exactly two
Added non-member function to subtract-absolutely
