Proof step 84 from proof bits2int-pos (previous step)

bits2uint((false ' + bitsinvert(bits0))+1) = 0, # bits0 ≤ 7 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 85:
⊦ true ∈ bits → bits2uint(bits) ≠ 0

Rule argument

seq: ⊦ true ∈ bits → bits2uint(bits) ≠ 0 subst: [bits] → [(false ' + bitsinvert(bits0))+1] rotate: F spec: int2bits inst: name: bits2uint-not-zero

Additional information

Used simplifier rules: ⊦ ¬ true ∈ bits → bits2uint(bits) = 0;% ⊦ ¬ true ∈ bits +1 ↔ false; Used terms: (false ' + bitsinvert(bits0))+1
