Proof step 7 from proof fits-law-mod (previous step)

i % b2i(by1) < ~128, i < 0, i % b2i(by1) < 0 ⊦ b2i(by1) = 0, i % b2i(by1) = b2i(i2b(i % b2i(by1)))

User applied rule cut formula

And obtained the following new goals

Proof step 8:
i % b2i(by1) < ~128, i < 0, i % b2i(by1) < 0 ⊦ b2i(by1) ≤ i % b2i(by1), b2i(by1) = 0, i % b2i(by1) = b2i(i2b(i % b2i(by1)))

Rule argument

fma: b2i(by1) ≤ i % b2i(by1)

Additional information

Used simplifier rules: byte-nls: ⊦ ¬ b2i(by) < ~128;% ⊦ i ≤ j ∧ j < j0 → i < j0; (forward) Used formulas: b2i(by1) ≤ i % b2i(by1)
