Proof step 26 from proof uint2bits-add-high-02 (previous step)

int2bits(j0) = boolvar ', j0 < 0, 0 < i, 2 ^ (i - 1) + j0 < 0, 0 ≤ j0 + 2 ^ i ⊦ i = 0, mklist(false, i→n(i)).first

User applied rule cut formula

And obtained the following new goals

Proof step 27:
boolvar, int2bits(j0) = boolvar ', j0 < 0, 0 < i, 2 ^ (i - 1) + j0 < 0, 0 ≤ j0 + 2 ^ i ⊦ i = 0, mklist(false, i→n(i)).first

Rule argument

fma: boolvar

Additional information

Used simplifier rules: int2bits-eq: ⊦ int2bits(j) = false ' ↔ j = 0;% ⊦ i + 0 = i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i;% ⊦ ¬ 2 ^ i < 0; Used formulas: boolvar
