Proof step 10 from proof cast-mod-ls-neg (previous step)

0 < i, 1 < i, i→n(i) < # int2bits(~1) ⊦ bits2int(lastn(i→n(i), int2bits(~1))) = ~1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 11:
⊦ i + 1 = 0 → int2bits(i) = true '

Rule argument

seq: ⊦ i + 1 = 0 → int2bits(i) = true ' subst: [i] → [~1] rotate: F spec: int2bits inst: name: int2bits-mone

Additional information

Used simplifier rules: ⊦ # boolvar ' = 0 +1;% ⊦ i < j → ¬ j < i;% ⊦ ¬ i ≤ j ↔ j < i;%0 ≤ i ⊦ i→n(i) < (* m) ↔ i < n→i(m);% ⊦ i < 1 ↔ i ≤ 0;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false); Used terms: ~1
