Proof step 15 from proof bits2int-sign (previous step)

⊦ bits2uint((false ' + bitsinvert(bits1))+1) = bits2uint(bitsinvert(bits) + (false ' + bitsinvert(bits1))+1), false ∈ bits

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 16:
⊦ ¬ true ∈ bits → bits2uint(bits + bits0) = bits2uint(bits0)

Rule argument

name: bits2uint-zeros-02 rotate: F subst: [bits0, bits] → [(false ' + bitsinvert(bits1))+1, bitsinvert(bits)]

Additional information

Used simplifier rules: ⊦ true ∈ bitsinvert(bits) ↔ false ∈ bits; Used terms: (false ' + bitsinvert(bits1))+1, bitsinvert(bits)
