soroban-fixed-point-math has Incorrect Rounding and Overflow Handling in Signed Fixed-Point Math with Negatives

Impact Incorrect rounding direction for signed mul and div operations The mulDivx, y, z function incorrectly handled cases where both the intermediate product $x y$ and the divisor $z$ were negative. The logic assumed that if the intermediate product was negative, the final result must also be...
