+
+/* ------------------------------------------------------------------ */
+/* Decimal Number arithmetic module */
+/* ------------------------------------------------------------------ */
+/* This module comprises the routines for General Decimal Arithmetic */
+/* as defined in the specification which may be found on the */
+/* http://www2.hursley.ibm.com/decimal web pages. It implements both */
+/* the full ('extended') arithmetic and the simpler ('subset') */
+/* arithmetic. */
+/* */
+/* Usage notes: */
+/* */
+/* 1. This code is ANSI C89 except: */
+/* */
+/* If DECDPUN>4 or DECUSE64=1, the C99 64-bit int64_t and */
+/* uint64_t types may be used. To avoid these, set DECUSE64=0 */
+/* and DECDPUN<=4 (see documentation). */
+/* */
+/* 2. The decNumber format which this library uses is optimized for */
+/* efficient processing of relatively short numbers; in particular */
+/* it allows the use of fixed sized structures and minimizes copy */
+/* and move operations. It does, however, support arbitrary */
+/* precision (up to 999,999,999 digits) and arbitrary exponent */
+/* range (Emax in the range 0 through 999,999,999 and Emin in the */
+/* range -999,999,999 through 0). Mathematical functions (for */
+/* example decNumberExp) as identified below are restricted more */
+/* tightly: digits, emax, and -emin in the context must be <= */
+/* DEC_MAX_MATH (999999), and their operand(s) must be within */
+/* these bounds. */
+/* */
+/* 3. Logical functions are further restricted; their operands must */
+/* be finite, positive, have an exponent of zero, and all digits */
+/* must be either 0 or 1. The result will only contain digits */
+/* which are 0 or 1 (and will have exponent=0 and a sign of 0). */
+/* */
+/* 4. Operands to operator functions are never modified unless they */
+/* are also specified to be the result number (which is always */
+/* permitted). Other than that case, operands must not overlap. */
+/* */
+/* 5. Error handling: the type of the error is ORed into the status */
+/* flags in the current context (decContext structure). The */
+/* SIGFPE signal is then raised if the corresponding trap-enabler */
+/* flag in the decContext is set (is 1). */
+/* */
+/* It is the responsibility of the caller to clear the status */
+/* flags as required. */
+/* */
+/* The result of any routine which returns a number will always */
+/* be a valid number (which may be a special value, such as an */
+/* Infinity or NaN). */
+/* */
+/* 6. The decNumber format is not an exchangeable concrete */
+/* representation as it comprises fields which may be machine- */
+/* dependent (packed or unpacked, or special length, for example). */
+/* Canonical conversions to and from strings are provided; other */
+/* conversions are available in separate modules. */
+/* */
+/* 7. Normally, input operands are assumed to be valid. Set DECCHECK */
+/* to 1 for extended operand checking (including NULL operands). */
+/* Results are undefined if a badly-formed structure (or a NULL */
+/* pointer to a structure) is provided, though with DECCHECK */
+/* enabled the operator routines are protected against exceptions. */
+/* (Except if the result pointer is NULL, which is unrecoverable.) */
+/* */
+/* However, the routines will never cause exceptions if they are */
+/* given well-formed operands, even if the value of the operands */
+/* is inappropriate for the operation and DECCHECK is not set. */
+/* (Except for SIGFPE, as and where documented.) */
+/* */
+/* 8. Subset arithmetic is available only if DECSUBSET is set to 1. */
+/* ------------------------------------------------------------------ */
+/* Implementation notes for maintenance of this module: */
+/* */
+/* 1. Storage leak protection: Routines which use malloc are not */
+/* permitted to use return for fastpath or error exits (i.e., */
+/* they follow strict structured programming conventions). */
+/* Instead they have a do{}while(0); construct surrounding the */
+/* code which is protected -- break may be used to exit this. */
+/* Other routines can safely use the return statement inline. */
+/* */
+/* Storage leak accounting can be enabled using DECALLOC. */
+/* */
+/* 2. All loops use the for(;;) construct. Any do construct does */
+/* not loop; it is for allocation protection as just described. */
+/* */
+/* 3. Setting status in the context must always be the very last */
+/* action in a routine, as non-0 status may raise a trap and hence */
+/* the call to set status may not return (if the handler uses long */
+/* jump). Therefore all cleanup must be done first. In general, */
+/* to achieve this status is accumulated and is only applied just */
+/* before return by calling decContextSetStatus (via decStatus). */
+/* */
+/* Routines which allocate storage cannot, in general, use the */
+/* 'top level' routines which could cause a non-returning */
+/* transfer of control. The decXxxxOp routines are safe (do not */
+/* call decStatus even if traps are set in the context) and should */
+/* be used instead (they are also a little faster). */
+/* */
+/* 4. Exponent checking is minimized by allowing the exponent to */
+/* grow outside its limits during calculations, provided that */
+/* the decFinalize function is called later. Multiplication and */
+/* division, and intermediate calculations in exponentiation, */
+/* require more careful checks because of the risk of 31-bit */
+/* overflow (the most negative valid exponent is -1999999997, for */
+/* a 999999999-digit number with adjusted exponent of -999999999). */
+/* */
+/* 5. Rounding is deferred until finalization of results, with any */
+/* 'off to the right' data being represented as a single digit */
+/* residue (in the range -1 through 9). This avoids any double- */
+/* rounding when more than one shortening takes place (for */
+/* example, when a result is subnormal). */
+/* */
+/* 6. The digits count is allowed to rise to a multiple of DECDPUN */
+/* during many operations, so whole Units are handled and exact */
+/* accounting of digits is not needed. The correct digits value */
+/* is found by decGetDigits, which accounts for leading zeros. */
+/* This must be called before any rounding if the number of digits */
+/* is not known exactly. */
+/* */
+/* 7. The multiply-by-reciprocal 'trick' is used for partitioning */
+/* numbers up to four digits, using appropriate constants. This */
+/* is not useful for longer numbers because overflow of 32 bits */
+/* would lead to 4 multiplies, which is almost as expensive as */
+/* a divide (unless a floating-point or 64-bit multiply is */
+/* assumed to be available). */
+/* */
+/* 8. Unusual abbreviations that may be used in the commentary: */
+/* lhs -- left hand side (operand, of an operation) */
+/* lsd -- least significant digit (of coefficient) */
+/* lsu -- least significant Unit (of coefficient) */
+/* msd -- most significant digit (of coefficient) */
+/* msi -- most significant item (in an array) */
+/* msu -- most significant Unit (of coefficient) */
+/* rhs -- right hand side (operand, of an operation) */
+/* +ve -- positive */
+/* -ve -- negative */
+/* ** -- raise to the power */

+/* and do not accumulate round-off (and any round-off errors in the */
+/* terms themselves move 'to the right' faster than they can */
+/* accumulate). This code also extends the calculation by allowing, */
+/* in the spirit of other decNumber operators, the input to be more */
+/* precise than the result (the precision used is based on the more */
+/* precise of the input or requested result). */
+/* */
+/* Implementation notes: */
+/* */
+/* 1. This is separated out as decExpOp so it can be called from */
+/* other Mathematical functions (notably Ln) with a wider range */
+/* than normal. In particular, it can handle the slightly wider */
+/* (double) range needed by Ln (which has to be able to calculate */
+/* exp(-x) where x can be the tiniest number (Ntiny). */
+/* */
+/* 2. Normalizing x to be <=0.1 (instead of <=1) reduces loop */
+/* iterations by appoximately a third with additional (although */
+/* diminishing) returns as the range is reduced to even smaller */
+/* fractions. However, h (the power of 10 used to correct the */
+/* result at the end, see below) must be kept <=8 as otherwise */
+/* the final result cannot be computed. Hence the leverage is a */
+/* sliding value (8-h), where potentially the range is reduced */
+/* more for smaller values. */
+/* */
+/* The leverage that can be applied in this way is severely */
+/* limited by the cost of the raise-to-the power at the end, */
+/* which dominates when the number of iterations is small (less */
+/* than ten) or when rhs is short. As an example, the adjustment */
+/* x**10,000,000 needs 31 multiplications, all but one full-width. */
+/* */
+/* 3. The restrictions (especially precision) could be raised with */
+/* care, but the full decNumber range seems very hard within the */
+/* 32-bit limits. */
