Proof step 47 from proof bib-neg-low (previous step)

int2bits(j) = boolvar ', i0 < 0, 256 * i0 + j < 0, j < 0, ~256 < j, 256 * i0 + j < ~128, j < ~128 ⊦ b2i(i2b(bits2int(mklist(false, 8)))) = 256 + j

And closed the goal!

Rule argument

fma: boolvar

Additional information

Used simplifier rules: ⊦ int2bits(j) = true ' ↔ j = ~1;% ⊦ int2bits(j) = false ' ↔ j = 0;% ⊦ i * j = j * i;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i; Used formulas: boolvar
