+ * rounding mode.

++ * Whenever a fraction is present, if the second or any following bit after
++ * the radix point is set, limit to the second radix point to avoid
++ * possible double rounding in the TWO52 +- steps (in case guard bits are
++ * used). Specifically, if have any, chop off bits past the 2nd place and
