C.16.IR:4.5 - Choose the useful return

Return the value, range or comparison with the conditions that support it. Stop when it is sufficient for the intended use. A lower bound can be more useful than an unnecessarily precise estimate.

For an unresolved decision, use the differing cases to choose a potentially useful next contribution: an available second reading, a different operating range, a better bound, a changed instrument or a narrower conclusion. Examine what that contribution could distinguish before obtaining it. In :5.3, another counter using a different modulus distinguishes alternatives that repeating the same remainder preserves.

Use C.11.DUA when the value and effort of reducing the ambiguity need comparison. It can be reasonable to act with the remaining uncertainty or leave the question unresolved. B.5.MPC.R coordinates a needed revision across the physical, mathematical and computational contributions.
