Proof step 5 from proof int2bytes-le255 (previous step)

127 < i, i ≤ 255, 0 < i, 0 ≤ i, # int2bits(i) ≤ 8 ⊦ i2b(i) ' = i2b(0) ' + i2b(i - 256) '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ 0 ≤ i → int2bits(i) = uint2bits(i)
Proof step 7:
0 ≤ i, 127 < i, i ≤ 255, 0 < i, 0 ≤ i, # uint2bits(i) ≤ 8 ⊦ i2b(i) ' = i2b(0) ' + i2b(i - 256) '

Rule argument

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