Proof step 1 from proof fix-two (conclusion)

⊦ fix(2, i2b(0) ') = i2b(0) ' + i2b(0) '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ # bytes < n ∧ 0 ≤ bytes2int(bytes) → fix(n, bytes) = mklist(i2b(0), n - # bytes) + bytes

Rule argument

name: fix-pos rotate: F subst: [bytes, n] → [i2b(0) ', 2]

Additional information

Used simplifier rules: bytes2int-zero: ⊦ bytes2int(i2b(0) ') = 0;% ⊦ # by ' = 0 +1;% ⊦ mklist(by, 1) = by ';% ⊦ bytes + bytes0 = bytes + bytes1 ↔ bytes0 = bytes1;% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1; Used terms: i2b(0) ', 2
