Proof step 43 from proof int2bytes-butlast (previous step)

i < 0, i ≤ ~256, i = ~256 ∨ i % 256 ≠ 0, i = ~256 ∨ i % 256 = 0 ⊦ int2bytes(i / 256) = int2bytes(i >> 8)

User applied rule cut formula

And obtained the following new goals

Proof step 44:
i = ~256, i < 0, i ≤ ~256, i = ~256 ∨ i % 256 ≠ 0, i = ~256 ∨ i % 256 = 0 ⊦ int2bytes(i / 256) = int2bytes(i >> 8)

Rule argument

fma: i = ~256

Additional information

Used simplifier rules: ⊦ i ≠ j → (i ≤ j ↔ i < j); Used formulas: i = ~256
