#1443 - this issue is fixed now because we use KaliskiModInverse for classical simulation instead of my hacky temp solution. |

| # toffoli cost for Kaliski Mod Inverse, n extra toffolis in ModNeg, 2n extra toffolis to do n | ||
| # 3-controlled toffolis in step 2. The expression is written with rationals because sympy | ||
| # comparison fails with floats. | ||
| assert total_toff == sympy.Rational(253, 2) * n**2 + sympy.Rational(391, 2) * n - 31 |
There was a problem hiding this comment.
something that might help here or in the future: when comparing sympy expressions, the equality operator tests for the same literal expression. If you want to test for mathematical equality x = y you can test simplify(x-y)==0

Removes ModInv shim as it is no longer used
Replaces it with KaliskiModInverse bloq in ECAdd
Improves the gate count test to match toffoli count expected with bloq swap
