Proof step 3 from proof fix-length (previous step)

¬ # bytes ≥ n ⊦ # fix(n, bytes) = n

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
# bytes < n ⊦ # fix(n, bytes) = n

Rule argument

Additional information

Used simplifier rules: ⊦ m < n → n ≠ 0;% ⊦ m < n → n ≠ 0; (forward)% ⊦ ¬ m ≤ n ↔ n < m;% ⊦ n ≥ m ↔ m ≤ n;
