Proof step 3 from proof int2bytes-leading-zeros (
previous step
)
i < 0, int2bytes(i) = i2b(0) ' + i2b(0) ' + bytes ⊦
User applied rule insert rewrite lemma
And obtained the following new goals
Proof step 4
:
⊦ i < 0 → int2bytes(i) ≠ i2b(0) ' + bytes
Rule argument
name: int2bytes-first-neg-01 rotate: F subst: [bytes, i] → [i2b(0) ' + bytes, i]
Additional information
Used terms: i2b(0) ' + bytes, i
