Implement fpclassify():

o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to , and provide double_t and float_t typedefs in . o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to and others (FLT_EVAL_METHOD, DECIMAL_DIG) to via . o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'. This was developed by David Schultz and myself with input from bde and fenner. PR: 23103 Submitted by: David Schultz (significant portions) Reviewed by: bde, fenner (earlier versions)

Use the correct values for LDBL_*. Libc doesn't completely support

long doubles at the moment (printf truncates them to doubles). However, long doubles to appear to work to the ranges listed in this commit on both -stable (4.5) and -current. There may be some slight rounding issues with long doubles, but that's an orthogonal issue to these constants. I've had this in my local tree for 3 months, and in my company's local tree for 15 months with no ill effects. Obtained from: NetBSD Not likely to like it: bde

$Id$ -> $FreeBSD$

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not

1997-02-22T09:48:43Z

ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

1997-01-14T07:20:47Z

This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Made all header files idempotent and moved incorrect common data from

1993-11-07T17:43:17Z

headers into a related source file. Added cons.h as first step towards moving i386/i386/cons.h to machine/cons.h where it belongs.

Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some

1993-10-16T14:40:57Z

minor cleanup. Added $Id$ to files that did not have any version info, etc

Added (protection) around negative constants, in case a program wants

1993-06-30T22:59:18Z

to use the negative of that constant. #define NEG_NUM -3 #define SAFE_NEG_NUM (-3) i = -NEG_NUM; /* Error --3 */ j = -SAFE_NEG_NUM /* Okay -(-3) */

Setting up for updated (usable) FPE atof/vfprintf/vfscanf fixes
