-- negative ulps
-- Note that since we are under X3.274 rules, the rounding here after
-- subtraction is from the leftmost digit of the operands, not the
-- result. Hence, for example: 'add642 add 1 -77e-9' becomes:
--
-- 1000000000 E-9
-- - 0000000077 E-9
-- ----------
-- 0999999923 E-9
--
-- which is rounded to 9 digits from the left (and including the leading
-- 0 in this case).
