%define somver 2
%define sover %somver.3.8
Name: qd
Version: 2.3.8
Release: alt3
Summary: C++/Fortran-90 double-double and quad-double package
License: BSD
Group: Sciences/Mathematics
Url: http://crd.lbl.gov/~dhbailey/mpdist/
Packager: Eugeny A. Rostovtsev (REAL) <real at altlinux.org>

Source: %name-%version.tar.gz

Requires: lib%name = %version-%release

%description
This package provides numeric types of twice the precision of IEEE
double (106 mantissa bits, or approximately 32 decimal digits) and
four times the precision of IEEE double (212 mantissa bits, or
approximately 64 decimal digits).  Due to features such as operator
and function overloading, these facilities can be utilized
with only minor modifications to conventional C++ and Fortran-90
programs.

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.
