+ *
+ * Motorola processors (Macintosh, Sun, Sparc, MIPS, etc)
+ * pack bytes from high to low (they are big-endian).

+ * Intel-like machines (PCs, Sequent)
+ * pack bytes from low to high (the are little-endian).
+ * Use the LowHigh routines to match the native format
+ * of these machines.
+ *
+ * These routines have been tested on the following machines:
+ *	Apple Macintosh, MPW 3.1 C compiler
+ *	Apple Macintosh, THINK C compiler
+ *	Silicon Graphics IRIS, MIPS compiler
+ *	Cray X/MP and Y/MP
+ *	Digital Equipment VAX
+ *
+ *
+ * Implemented by Malcolm Slaney and Ken Turkowski.
+ *
+ * Malcolm Slaney contributions during 1988-1990 include big- and little-
+ * endian file I/O, conversion to and from Motorola's extended 80-bit
+ * FLOATing-point format, and conversions to and from IEEE single-
+ * precision FLOATing-point format.
+ *
+ * In 1991, Ken Turkowski implemented the conversions to and from
+ * IEEE double-precision format, added more precision to the extended
+ * conversions, and accommodated conversions involving +/- infinity,
+ * NaN's, and denormalized numbers.
