Proof step 14 from proof int2bits-mod2pot (previous step)

0 ≤ i, j0 < 2 ^ i, 0 ≤ j0, 0 < j, 2 ^ i ≤ j * 2 ^ i + j0, 0 < j * 2 ^ i + j0, 0 < 2 ^ i, 0 ≤ j ⊦ fillsgn(i→n(i) + 1, uint2bits(j0)).rest = fillsgn(i→n(i) + 1, int2bits(j0)).rest

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 15:
⊦ 0 ≤ i → int2bits(i) = uint2bits(i)

Rule argument

name: int2bits-pos rotate: F subst: [i] → [j0]

Additional information

Used simplifier rules: ⊦ m + n = n + m; Used terms: j0
