 /* This is a variation on dtoa.c that converts arbitary binary

    floating-point formats to and from decimal notation.  It uses

    double-precision arithmetic internally, so there are still

    various #ifdefs that adapt the calculations to the native

    double-precision arithmetic (any of IEEE, VAX D_floating,

    or IBM mainframe arithmetic).

 /* On a machine with IEEE extended-precision registers, it is

  * necessary to specify double-precision (53-bit) rounding precision

  * before invoking strtod or dtoa.  If the machine uses (the equivalent

  * of) Intel 80x87 arithmetic, the call

  *	_control87(PC_53, MCW_PC);

  * does this with many compilers.  Whether this or another call is

  * appropriate depends on the compiler; for this to work, it may be

  * necessary to #include "float.h" or another system-dependent header

  * file.

  */

 /* strtod for IEEE-, VAX-, and IBM-arithmetic machines.

  *

  * This strtod returns a nearest machine number to the input decimal

  * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are

  * broken by the IEEE round-even rule.  Otherwise ties are broken by

  * biased rounding (add half and chop).

  *

  * Inspired loosely by William D. Clinger's paper "How to Read Floating

  * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].

  *

  * Modifications:

  *

  *	1. We only require IEEE, IBM, or VAX double-precision

  *		arithmetic (not IEEE double-extended).

  *	2. We get by with floating-point arithmetic in a case that

  *		Clinger missed -- when we're computing d * 10^n

  *		for a small integer d and the integer n is not too

  *		much larger than 22 (the maximum integer k for which

  *		we can represent 10^k exactly), we may be able to

  *		compute (d*10^k) * 10^(e-k) with just one roundoff.

  *	3. Rather than a bit-at-a-time adjustment of the binary

  *		result in the hard case, we use floating-point

  *		arithmetic to determine the adjustment to within

  *		one bit; only in really hard cases do we need to

  *		compute a second residual.

  *	4. Because of 3., we don't need a large table of powers of 10

  *		for ten-to-e (just some small tables, e.g. of 10^k

  *		for 0 <= k <= 22).

 /*

  * #define IEEE_8087 for IEEE-arithmetic machines where the least

  *	significant byte has the lowest address.

  * #define IEEE_MC68k for IEEE-arithmetic machines where the most

  *	significant byte has the lowest address.

  * #define Long int on machines with 32-bit ints and 64-bit longs.

  * #define Sudden_Underflow for IEEE-format machines without gradual

  *	underflow (i.e., that flush to zero on underflow).

  * #define IBM for IBM mainframe-style floating-point arithmetic.

  * #define VAX for VAX-style floating-point arithmetic (D_floating).

  * #define No_leftright to omit left-right logic in fast floating-point

  *	computation of dtoa.

  * #define Check_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3.

  * #define RND_PRODQUOT to use rnd_prod and rnd_quot (assembly routines

  *	that use extended-precision instructions to compute rounded

  *	products and quotients) with IBM.

  * #define ROUND_BIASED for IEEE-format with biased rounding.

  * #define Inaccurate_Divide for IEEE-format with correctly rounded

  *	products but inaccurate quotients, e.g., for Intel i860.

  * #define NO_LONG_LONG on machines that do not have a "long long"

  *	integer type (of >= 64 bits).  On such machines, you can

  *	#define Just_16 to store 16 bits per 32-bit Long when doing

  *	high-precision integer arithmetic.  Whether this speeds things

  *	up or slows things down depends on the machine and the number

  *	being converted.  If long long is available and the name is

  *	something other than "long long", #define Llong to be the name,

  *	and if "unsigned Llong" does not work as an unsigned version of

  *	Llong, #define #ULLong to be the corresponding unsigned type.

  * #define KR_headers for old-style C function headers.

  * #define Bad_float_h if your system lacks a float.h or if it does not

  *	define some or all of DBL_DIG, DBL_MAX_10_EXP, DBL_MAX_EXP,

  *	FLT_RADIX, FLT_ROUNDS, and DBL_MAX.

  * #define MALLOC your_malloc, where your_malloc(n) acts like malloc(n)

  *	if memory is available and otherwise does something you deem

  *	appropriate.  If MALLOC is undefined, malloc will be invoked

  *	directly -- and assumed always to succeed.

  * #define Omit_Private_Memory to omit logic (added Jan. 1998) for making

  *	memory allocations from a private pool of memory when possible.

  *	When used, the private pool is PRIVATE_MEM bytes long:  2304 bytes,

  *	unless #defined to be a different length.  This default length

  *	suffices to get rid of MALLOC calls except for unusual cases,

  *	such as decimal-to-binary conversion of a very long string of

  *	digits.  When converting IEEE double precision values, the

  *	longest string gdtoa can return is about 751 bytes long.  For

  *	conversions by strtod of strings of 800 digits and all gdtoa

  *	conversions of IEEE doubles in single-threaded executions with

  *	8-byte pointers, PRIVATE_MEM >= 7400 appears to suffice; with

  *	4-byte pointers, PRIVATE_MEM >= 7112 appears adequate.

  * #define INFNAN_CHECK on IEEE systems to cause strtod to check for

  *	Infinity and NaN (case insensitively).  On some systems (e.g.,

  *	some HP systems), it may be necessary to #define NAN_WORD0

  *	appropriately -- to the most significant word of a quiet NaN.

  *	(On HP Series 700/800 machines, -DNAN_WORD0=0x7ff40000 works.)

  *	When INFNAN_CHECK is #defined and No_Hex_NaN is not #defined,

  *	strtodg also accepts (case insensitively) strings of the form

  *	NaN(x), where x is a string of hexadecimal digits and spaces;

  *	if there is only one string of hexadecimal digits, it is taken

  *	for the fraction bits of the resulting NaN; if there are two or

  *	more strings of hexadecimal digits, each string is assigned

  *	to the next available sequence of 32-bit words of fractions

  *	bits (starting with the most significant), right-aligned in

  *	each sequence.

  * #define MULTIPLE_THREADS if the system offers preemptively scheduled

  *	multiple threads.  In this case, you must provide (or suitably

  *	#define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed

  *	by FREE_DTOA_LOCK(n) for n = 0 or 1.  (The second lock, accessed

  *	in pow5mult, ensures lazy evaluation of only one copy of high

  *	powers of 5; omitting this lock would introduce a small

  *	probability of wasting memory, but would otherwise be harmless.)

  *	You must also invoke freedtoa(s) to free the value s returned by

  *	dtoa.  You may do so whether or not MULTIPLE_THREADS is #defined.

  * #define IMPRECISE_INEXACT if you do not care about the setting of

  *	the STRTOG_Inexact bits in the special case of doing IEEE double

  *	precision conversions (which could also be done by the strtog in

  *	dtoa.c).

  * #define NO_HEX_FP to disable recognition of C9x's hexadecimal

  *	floating-point constants.

  * #define -DNO_ERRNO to suppress setting errno (in strtod.c and

  *	strtodg.c).

  * #define NO_STRING_H to use private versions of memcpy.

  *	On some K&R systems, it may also be necessary to

  *	#define DECLARE_SIZE_T in this case.

  * #define YES_ALIAS to permit aliasing certain double values with

  *	arrays of ULongs.  This leads to slightly better code with

  *	some compilers and was always used prior to 19990916, but it

  *	is not strictly legal and can cause trouble with aggressively

  *	optimizing compilers (e.g., gcc 2.95.1 under -O2).

  * #define USE_LOCALE to use the current locale's decimal_point value.
