Proof step 2 from proof int2bits-leading-sgn (previous step)

¬ 0 ≤ i ↔ int2bits(i).rest.first ⊦ # int2bits(i) = 1

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, ¬ 0 ≤ i ↔ int2bits(i).rest.first ⊦ # int2bits(i) = 1
Proof step 8:
0 ≤ i, ¬ 0 ≤ i ↔ uint2bits(i).rest.first ⊦ # uint2bits(i) = 1

Rule argument

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