Proof step 8 from proof int2bytes-rec-case (previous step)

0 ≤ i, 0 < i, 128 ≤ i, i < 256 ⊦ int2bytes(i) = i2b(0) ' + i2b(i - 256) '

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
127 < i, i ≤ 255 ⊦ int2bytes(i) = i2b(0) ' + i2b(i - 256) '

Rule argument

name: int2bytes-le255 rotate: F subst: [i] → [i]

Additional information

Used simplifier rules: i0 ≠ 0, i0 < i ⊦ (* i) ≤ j → (* i0) < j;% ⊦ ¬ i ≤ j ↔ j < i;%i + 1 = i0 ⊦ j < (* i0) → ¬ (* i) < j; Used terms: i
