Proof step 1 from proof int2bits-first-06 (conclusion)

⊦ int2bits(i) = boolvar ' + bits ∧ i < 0 → boolvar

Heuristic simplifier applied rule simplifier

And closed the goal!

Rule argument

Additional information

Used simplifier rules: int2bits-first: ⊦ j < 0 → int2bits(j) ≠ false ' + bits;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;
