Proof step 2 from proof bits2int-ones (previous step)

⊦ bits = [], bits2int(bits) = ~1, false ∈ bits

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ bits2int(sgn(bits)) = bits2int(bits)

Rule argument

name: bits2int-sgn rotate: T subst: [bits] → [bits]

Additional information

Used simplifier rules: bits2int-one: ⊦ bits2int(true ') = ~1;% ⊦ ¬ false ∈ bits ∧ bits ≠ [] → sgn(bits) = true '; Used terms: bits
