Proof step 1 from proof bint-and-011x-bits2unit (conclusion)

⊦ i ∈bint → (bits2uint(fillsgn(32, int2bits(i))) ≠ band(4294967295, i) ↔ false)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
~2147483648 ≤ i, i ≤ 2147483647 ⊦ bits2uint(fillsgn(32, int2bits(i))) = band(4294967295, i)

Rule argument

Additional information

Used simplifier rules: inbint: ⊦ i ∈bint ↔ ~2147483648 ≤ i ∧ i ≤ 2147483647;% ⊦ j ≤ j0 ∧ j0 ≤ j1 → j ≤ j1; (forward)
