Derivation

  1. Split input into 2 regimes

  2. if y < -2.695791018707365e-48 or 3.434074777275514e-112 < y

    1. Initial program 13.7

      \[\left(x \cdot \left(y \cdot z - t \cdot a\right) - b \cdot \left(c \cdot z - i \cdot a\right)\right) + j \cdot \left(c \cdot t - i \cdot y\right)\]
    2. Using strategy rm
