Derivation

1. Split input into 2 regimes

2. if z < -1.10000000000000002e-113 or 1.2600000000000001e-152 < z

   1. Initial program 85.2%

      \[x + \frac{\left(y - z\right) \cdot t}{a - z} \]

   2. Taylor expanded in z around inf

      \[\leadsto x + \color{blue}{t} \]

   4. Applied rewrites 59.9%

      \[\leadsto x + \color{blue}{t} \]

   if -1.10000000000000002e-113 < z < 1.2600000000000001e-152

   1. Initial program 85.2%

      \[x + \frac{\left(y - z\right) \cdot t}{a - z} \]

   3. Applied rewrites 95.9%

      \[\leadsto \color{blue}{\mathsf{fma}\left(y - z, \frac{t}{a - z}, x\right)} \]

   4. Taylor expanded in x around inf

      \[\leadsto \color{blue}{x \cdot \left(1 + \frac{t \cdot \left(y - z\right)}{x \cdot \left(a - z\right)}\right)} \]

   6. Applied rewrites 78.4%

      \[\leadsto \color{blue}{x \cdot \left(1 + \frac{t \cdot \left(y - z\right)}{x \cdot \left(a - z\right)}\right)} \]

   7. Taylor expanded in x around inf

      \[\leadsto x \cdot 1 \]

   9. Applied rewrites 50.0%

      \[\leadsto x \cdot 1 \]
3. Recombined 2 regimes into one program.
4. Add Preprocessing
