QD is a package that supports both a double-double datatype with about 32 decimal digits,
and a quad-double datatype with about 64 decimal digits.
The library is written by David H. Bailey et. al from the Lawrence Berkeley National Laboratory (see http://crd.lbl.gov/~dhbailey/mpdist).
In addition to the basic arithmetic operations (add, subtract,
multiply, divide, square root), common transcendental functions such
as the exponential, logarithm, trigonometric and hyperbolic functions
are also included.
