Under the assumption that input will be rounded nearest, + mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22. + That is, we allow equality in stopping tests when the + round-nearest rule will give the same floating-point value + as would satisfaction of the stopping test with strict + inequality. + 4. 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.
