A conversion audit is accepted only when both clipping boundaries are evidenced. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Endpoint high clip and one-volt low clip close the audit
High input 8 V and low input -1 V both clip, so accepted flag is 1.
8V,−1V⇒A=1
Outside high and outside low clips still close the audit
High input 10 V and low input -2 V both clip, so accepted flag is 1.
10V,−2V⇒A=1
Far boundary examples remain clipped before acceptance
High input 12 V and low input -4 V both clip, so accepted flag is 1.
