code[x_, y_, z_] := If[LessEqual[y, 2.65e-80], x, y]

Derivation

1. Split input into 2 regimes

2. if y < 2.65000000000000013e-80

   1. Initial program 99.9%

      \[\left(x + y\right) \cdot \left(1 - z\right) \]
   2. Add Preprocessing

   3. Taylor expanded in z around 0 47.0%

      \[\leadsto \color{blue}{x + y} \]
   4. Step-by-step derivation

      1. +-commutative 47.0%

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

   5. Simplified 47.0%

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

   6. Taylor expanded in y around 0 31.3%

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

   if 2.65000000000000013e-80 < y

   1. Initial program 100.0%

      \[\left(x + y\right) \cdot \left(1 - z\right) \]
   2. Add Preprocessing

   3. Taylor expanded in z around 0 52.0%

      \[\leadsto \color{blue}{x + y} \]
   4. Step-by-step derivation

      1. +-commutative 52.0%

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

   5. Simplified 52.0%

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

   6. Taylor expanded in y around inf 43.0%

      \[\leadsto \color{blue}{y} \]
3. Recombined 2 regimes into one program.
4. Add Preprocessing
