Proof step 23 from proof bib-on-bits (
previous step
)
¬ i ∈byte ⊦ b2i(i2b(bits2int(lastn(8, int2bits(i))))) = bits2int(lastn(8, fillsgn(8, int2bits(i))))
Heuristic simplifier applied rule simplifier
And obtained the following new goals
Proof step 24
:
⊦ b2i(i2b(bits2int(lastn(8, int2bits(i))))) = bits2int(lastn(8, fillsgn(8, int2bits(i)))), i ∈byte
