Proof step 2 from proof bytes2int-le-zero (previous step)

⊦ bytes2int(i2b(0) ' + bytes) = 0, bytes2int(i2b(0) ' + bytes) ≤ 0 ↔ bytes2int(i2b(0) ' + bytes) = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
bytes2int(i2b(0) ' + bytes) < 0 ⊦ bytes2int(i2b(0) ' + bytes) = 0

Rule argument

Additional information

Used simplifier rules: ⊦ j < i ∧ i ≤ 0 → j < 0; (forward)% ⊦ i ≠ j → (i ≤ j ↔ i < j);
