A royalty-free C++ numeric class has been developed that extends
range of values that the exponent field in a floating point double class
may assume.  The class includes overloads for all common mathematical
operators and functions that include this extended-range class as
operands or parameters.  Software for testing and timing this numeric
class on a target platform are also provided.  The software package for
the extended range class has been successfully tested on Linux, Windows
95, Sun Solaris, and SGI IRIX platforms.

The class was developed by the National Biotechnology Information
Facility, and is available for download via the NBIF WWW site:
