| * 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 |
| * Sequent Balance (Multiprocesor 386) |
| * NeXT |
| * |
| * |
| * 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. |
