\(\begin{cases} (\left(x - a\right) * \left(\frac{y}{z}\right) + a)_* & \text{when } z \le -2.4724579276140303 \cdot 10^{+244} \\ (\left(a - x\right) * \left(\frac{1}{\frac{\left(1.0 + t\right) - z}{y - z}}\right) + x)_* & \text{when } z \le 1.7059758340520525 \cdot 10^{+174} \\ (\left(x - a\right) * \left(\frac{y}{z}\right) + a)_* & \text{otherwise} \end{cases}\)

    if z < -2.4724579276140303e+244 or 1.7059758340520525e+174 < z

    1. Started with
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)\]
      31.0
    2. Applied simplify to get
      \[\color{red}{x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)} \leadsto \color{blue}{(\left(a - x\right) * \left(\frac{y - z}{\left(1.0 + t\right) - z}\right) + x)_*}\]
      31.0
    3. Using strategy rm
      31.0
    4. Applied fma-udef to get
      \[\color{red}{(\left(a - x\right) * \left(\frac{y - z}{\left(1.0 + t\right) - z}\right) + x)_*} \leadsto \color{blue}{\left(a - x\right) \cdot \frac{y - z}{\left(1.0 + t\right) - z} + x}\]
      31.0
    5. Applied taylor to get
      \[\left(a - x\right) \cdot \frac{y - z}{\left(1.0 + t\right) - z} + x \leadsto \left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}\]
      11.9
    6. Taylor expanded around inf to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}}\]
      11.9
    7. Applied simplify to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{(\left(x - a\right) * \left(\frac{y}{z}\right) + a)_*}\]
