This package permits a scientist to perform computations using a precision level of either 32 or 64 decimal digits, by making only minor changes to conventional C++ or Fortran-90 source code. This software takes advantage of certain properties of IEEE floating-point arithmetic, together with advanced numeric algorithms, custom datatypes and operator overloading.
