*math.h - definitions and declarations for math library
*
* Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This file contains constant definitions and external subroutine
* declarations for the math subroutine library.
* [ANSI/System V]
*
*Revision History:
* 10/20/87 JCR Removed "MSC40_ONLY" entries
* 12-11-87 JCR Added "_loadds" functionality
* 12-18-87 JCR Added _FAR_ to declarations
* 02-10-88 JCR Cleaned up white space
* 02-10-88 WAJ Changed HUGE and HUGE_VAL definitions for DLL libraries
* 05-32-88 PHG Added _CDECL and _NEAR for declaration of HUGE
* 08-22-88 GJF Modified to also work with the 386 (small model only)
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
* 08-02-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright
* 11-02-89 JCR Changed "DLL" to "_DLL"
* 11-20-89 JCR Routines are now _cdecl in both single and multi-thread
* 12-14-89 WAJ Removed pascal from mthread version.
* 03-01-90 GJF Added #ifndef _INC_MATH and #include <cruntime.h>
* stuff. Also, removed some (now) useless preprocessor
* directives.
* 03-29-90 GJF Replaced _cdecl with _VARTYPE1, _CALLTYPE1 or
* _CALLTYPE2, as appropriate.
* 07-30-90 SBM Removed special _DLL definitions of HUGE and HUGE_VAL
* 08-17-90 WAJ Floating point routines now use _stdcall.
* 08-08-91 GJF Added long double stuff. ANSI naming.
* 08-20-91 JCR C++ and ANSI naming
* 09-28-91 JCR ANSI names: DOSX32=prototypes, WIN32=#defines for now
* 10-03-91 GDP Added #pragma function(...)
* No floating point intrinsics for WIN32/NT86
* 10-06-91 SRW Removed long double stuff.
* 01-24-92 GJF Fixed [_]HUGE for crtdll.dll.
* 01-30-92 GJF Removed prototypes and macros for the ieee-to/from-
* msbin functions (they don't exist).
* 08-05-92 GJF Function calling type and variable type macros.
* 12-18-92 GDP Removed #pragma function(...)
* 01-21-93 GJF Removed support for C6-386's _cdecl.
* 11-17-93 CFW Fixed HUGE (oldname) macro, now maps to _HUGE.
* 01-13-94 RDL Added #ifndef _LANGUAGE_ASSEMBLY for asm includes.
