333 * "Normalize" the terms in the infinite-precision expression a + b for

335 * relative to 'a'. (The resulting 'a' is the value of the expression in
336 * the same precision as 'a' and the resulting b is the rounding error.)
337 * |a| must be >= |b| or 0, b's type must be no larger than 'a's type, and
338 * exponent overflow or underflow must not occur. This uses a Theorem of
339 * Dekker (1971). See Knuth (1981) 4.2.2 Theorem C. The name "TwoSum"
340 * is apparently due to Skewchuk (1997).
341 *
342 * For this to always work, assignment of a + b to 'a' must not retain any
343 * extra precision in a + b. This is required by C standards but broken
344 * in many compilers. The brokenness cannot be worked around using
345 * STRICT_ASSIGN() like we do elsewhere, since the efficiency of this
346 * algorithm would be destroyed by non-null strict assignments. (The
347 * compilers are correct to be broken -- the efficiency of all floating
348 * point code calculations would be destroyed similarly if they forced the
349 * conversions.)
350 *
351 * Fortunately, a case that works well can usually be arranged by building
352 * any extra precision into the type of 'a' -- 'a' should have type float_t,
353 * double_t or long double. b's type should be no larger than 'a's type.
354 * Callers should use these types with scopes as large as possible, to
355 * reduce their own extra-precision and efficiciency problems. In
356 * particular, they shouldn't convert back and forth just to call here.

394 * can be normalized without extra work to swap 'a' with c). The details of
395 * the normalization are that b must be small relative to the normalized 'a'.

399 * 2**20 times smaller than 'a' to give about 20 extra bits of precision.
400 * That is usually enough, and adding c (which by normalization is about
401 * 2**53 times smaller than a) cannot change b significantly. However,
