Proof step 8 from proof int2bytes-zero (previous step)

int2bytes(i) = i2b(0) ', i ≤ 127 ⊦ i = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
~128 ≤ i, i < 128 ⊦ int2bytes((* i)) = i2b(i) '
Proof step 10:
¬(~128 ≤ i ∧ i < 128), int2bytes(i) = i2b(0) ', i ≤ 127 ⊦ i = 0
Proof step 13:
~128 ≤ i ∧ i < 128, i2b(i) ' = i2b(0) ', i ≤ 127 ⊦ i = 0

Rule argument

name: int2bytes-byte rotate: F subst: [i] → [i]
