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 +t' ≤ 2^(u−3) = 2^(−3) ulp in absolute value, so that the error ε on the +significand satisfies −t' ≤ ε < 1 ulp + t'.
