 just above. We currently have a significand, a trailing term t in the
 accumulator such that 0 ≤ t < 1 ulp (non-negative thanks to the two's
 complement representation), and an error on the trailing term bounded by
-t' ≤ 2^(u−3) = 2^(−3) ulp in absolute value, so that the error e on the
-significand satisfies −t' ≤ e < 1 ulp + t'. Thus one has 4 correction
