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. + */ + +#ifndef GDTOAIMP_H_INCLUDED +#define GDTOAIMP_H_INCLUDED +#include "gdtoa.h" + +#ifdef DEBUG +#include "stdio.h" +#define Bug(x) {fprintf(stderr, "%s\n", x);
