All rights reserved.**Purpose:* Declares floating point types, routines and variables used* internally by the C run-time.** [Internal]**Revision History:* 10-20-88 JCR Changed 'DOUBLE' to 'double' for 386* 08-15-89 GJF Fixed copyright, indents* 10-30-89 GJF Fixed copyright (again)* 03-02-90 GJF Added #ifndef _INC_STRUCT stuff. Also, cleaned up* the formatting a bit.* 03-05-90 GJF Fixed up the arg types in protoypes. Also, added* #include <cruntime.h>* 03-22-90 GJF Made _fltin(), _fltin2(), _fltout() and _fltout2()* _CALLTYPE2 (for now) and added a prototype for* _fptostr().* 08-01-90 SBM Moved _cftoe() and _cftof() here from internal.h* and _cfltcvt_tab from input.c and output.c,* added typedefs for _cfltcvt_tab entries,* renamed module from <struct.h> to <fltintrn.h> and* adjusted #ifndef stuff to #ifndef _INC_FLTINTRN* 08-29-90 SBM Changed type of _cfltcvt_tab[] to agree with* definition in cmiscdat.c* 04-26-91 SRW Removed level 3 warnings* 08-26-91 JCR Changed MIPS to _MIPS_, ANSI naming* 08-06-92 GJF Function calling type and variable type macros. Revised* use of target processor macros.* 11-09-92 GJF Fixed preprocessing conditionals for MIPS.* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI* Use _MIPS_ and _ALPHA_ instead.* 01-21-93 GJF Removed support for C6-386's _cdecl.* 04-06-93 SKS Replace _CRTAPI1/2 with __cdecl, _CRTVAR1 with nothing* 09-01-93 GJF Merged Cuda and NT SDK versions.* 10-13-93 GJF Dropped _MIPS_. Replaced _ALPHA_ with _M_ALPHA.* 10-29-93 GJF Disabled the ever-annoying 4069 warning.* 10-02-94 BWT Add PPC support.* 12-15-94 XY merged with mac header* 02-14-95 CFW Clean up Mac merge.* 03-29-95 CFW Add error message to internal headers.* 12-14-95 JWM Add "#pragma once".* 02-05-97 GJF Deleted obsolete support for _CRTAPI* and _NTSDK.* Replaced (defined(_M_MPPC) || defined(_M_M68K)) with* defined(_MAC) where appropriate. Replaced _CALLTYPE2* with __cdecl. Also, detab-ed.* 05-17-99 PML Remove all Macintosh support.* 09-05-00 GB Changed the defination of fltout functions. Use DOUBLE * instead of double*****/
