+ * Machine-independent I/O routines for IEEE floating-point numbers.
+ *
+ * NaN's and infinities are converted to HUGE_VAL or HUGE, which
+ * happens to be infinity on IEEE machines.  Unfortunately, it is
+ * impossible to preserve NaN's in a machine-independent way.
+ * Infinities are, however, preserved on IEEE 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.
