Below, equal, and above threshold rows show the inclusive energy gate. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Negative margin rejects
Available energy 180 J minus required 200 J gives margin -20 J and accepted bit 0.
180−200=−20,a=0
Zero margin passes exactly at threshold
Available energy 200 J minus required 200 J gives margin 0 J and accepted bit 1.
200−200=0,a=1
Positive margin also passes
Available energy 260 J minus required 200 J gives margin 60 J and accepted bit 1.
