TOMS722
IEEE Arithmetic Support


TOMS722 is a C library which supports IEEE arithmetic. Both single and double precision routines are supplied.

Compilation of the functions requires specifying a compiler flag that indicates whether big-endian or little-endian storage is used, and whether graceful underflow occurs.

The current results used the compiler flag "-DBEG", but there are four pairs of computations that had to be commented out in order for the tests to run.

The original, correct and authentic copies of the source code are available from the TOMS subdirectory of NETLIB.
