A Double-Double and Quad-Double Arithmetic library.
|
|
Double-double and quad-double numbers are unevaluated sum of
|
|
two and four IEEE doubles capable of representing 106 and 212 bits
|
|
of significand, respectively. The library is written in C++, taking full
|
|
advantage of operator overloading. C, Fortran 77, and Fortran 90 interfaces
|
|
are also provided.
