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. * * $Id: ieeefloat.h,v 1.1 1993/06/11 17:45:46 malcolm Exp $ * * $Log: ieeefloat.h,v $ * Revision 1.1  1993/06/11  17:45:46  malcolm * Initial revision * */#include	<math.h>typedef float Single;#ifndef applec typedef double defdouble;#else /* !applec */ typedef long double defdouble;#endif /* applec */#ifndef THINK_C typedef double Double;#else /* THINK_C */ typedef short double Double;#endif /* THINK_C */#define	kFloatLength	4#define	kDoubleLength	8#define	kExtendedLength	10extern defdouble ConvertFromIeeeSingle(char *bytes);extern void ConvertToIeeeSingle(defdouble num, char *bytes);extern defdouble ConvertFromIeeeDouble(char *bytes);extern void ConvertToIeeeDouble(defdouble num, char *bytes);extern defdouble ConvertFromIeeeExtended(char *bytes);extern void ConvertToIeeeExtended(defdouble num, char *bytes);#endif
