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). - */ + \enum QLocale::CurrencySymbolFormat -/* - * #define IEEE_LITTLE_ENDIAN for IEEE-arithmetic machines where the least - * significant byte has the lowest address. - * #define IEEE_BIG_ENDIAN 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. - * #define Unsigned_Shifts if >> does treats its left operand as unsigned. - * #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 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. - * #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.

We remove common factors of powers of 2 from relevant - * quantities. - * 5. When converting floating-point integers less than 1e16, - * we use floating-point arithmetic rather than resorting - * to multiple-precision integers. - * 6. When asked to produce fewer than 15 digits, we first try - * to get by with floating-point arithmetic; we resort to - * multiple-precision integer arithmetic only if we cannot - * guarantee that the floating-point calculation has given - * the correctly rounded result.
