Average Error: 0.0 → 0.0

Time: 1.5s

Precision: binary64

Math

\[200 \cdot \left(x - y\right)\]

↓

\[200 \cdot x + 200 \cdot \left(-y\right)\]

Error

Bits error versus x

Bits error versus y

Derivation

1. Initial program 0.0

   \[200 \cdot \left(x - y\right)\]
2. Using strategy rm

3. Applied sub-neg 0.0

   \[\leadsto 200 \cdot \color{blue}{\left(x + \left(-y\right)\right)}\]

4. Applied distribute-lft-in 0.0

   \[\leadsto \color{blue}{200 \cdot x + 200 \cdot \left(-y\right)}\]

5. Final simplification 0.0

   \[\leadsto 200 \cdot x + 200 \cdot \left(-y\right)\]
