Proof step 2 from proof int2bytes-rec-pos (previous step)

255 < i, 0 < i, 0 ≤ i ⊦ bits2bytes(int2bits(i)) = bits2bytes(int2bits(i / 256)) + bits2bytes(int2bits(i % 256)).last '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 0 ≤ i → int2bits(i) = uint2bits(i)
Proof step 4:
0 ≤ i, 255 < i, 0 < i, 0 ≤ i ⊦ bits2bytes(uint2bits(i)) = bits2bytes(int2bits(i / 256)) + bits2bytes(int2bits(i % 256)).last '

Rule argument

seq: ⊦ 0 ≤ i → int2bits(i) = uint2bits(i) subst: [i] → [i] rotate: F spec: int2bits inst: name: int2bits-pos
