Proof step 2 from proof fix-value (previous step)

# bytes ≤ n ⊦ bytes = [], bytes2int(fix(n, bytes)) = bytes2int(bytes)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ # bytes ≥ n → fix(n, bytes) = lastn(n, bytes)
Proof step 4:
¬ # bytes ≥ n, # bytes ≤ n ⊦ bytes = [], bytes2int(fix(n, bytes)) = bytes2int(bytes)

Rule argument

name: fix-longer rotate: F subst: [bytes, n] → [bytes, n]

Additional information

Used simplifier rules: ⊦ n ≥ m ↔ m ≤ n;% ⊦ m ≤ n → (n ≤ m ↔ m = n);% ⊦ n = # bytes → lastn(n, bytes) = bytes; Used terms: bytes, n
