  17  * Machine-independent I/O routines for 8-, 16-, 24-, and 32-bit integers.
  18  *
  19  * Motorola processors (Macintosh, Sun, Sparc, MIPS, etc)
  20  * pack bytes from high to low (they are big-endian).
  21  * Use the HighLow routines to match the native format
  22  * of these machines.
  23  *
  24  * Intel-like machines (PCs, Sequent)
  25  * pack bytes from low to high (the are little-endian).
  26  * Use the LowHigh routines to match the native format
  27  * of these machines.
  28  *
  29  * These routines have been tested on the following machines:
  30  *      Apple Macintosh, MPW 3.1 C compiler
  31  *      Apple Macintosh, THINK C compiler
  32  *      Silicon Graphics IRIS, MIPS compiler
  33  *      Cray X/MP and Y/MP
  34  *      Digital Equipment VAX
  35  *
  36  *
  37  * Implemented by Malcolm Slaney and Ken Turkowski.
  38  *
  39  * Malcolm Slaney contributions during 1988-1990 include big- and little-
  40  * endian file I/O, conversion to and from Motorola's extended 80-bit
  41  * floating-point format, and conversions to and from IEEE single-
  42  * precision floating-point format.
  43  *
  44  * In 1991, Ken Turkowski implemented the conversions to and from
  45  * IEEE double-precision format, added more precision to the extended
  46  * conversions, and accommodated conversions involving +/- infinity,
  47  * NaN's, and denormalized numbers.
