Proof step 31 from proof band-max (previous step)

1 < bits2uint(int2bits(j).last '), 0 < bits2uint(int2bits(j).last '), ∀ i0, j. i→n(i0) < i→n(1) → i0 < bits2int(bitsand(int2bits(i0), int2bits(j))) ∧ 0 ≤ i0 → false ⊦ j = ~1, j = 0, int2bits(j) = (¬ 0 < j)', int2bits(j).butlast = []

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 32:
⊦ boolvar → bits2uint(boolvar ') = 1

Rule argument

seq: ⊦ boolvar → bits2uint(boolvar ') = 1 subst: [boolvar] → [int2bits(j).last] rotate: F spec: int2bits inst: name: bits2uint-one-01

Additional information

Used simplifier rules: ⊦ bits2uint(false ') = 0; Used terms: int2bits(j).last
