Error

Bits error versus f

Bits error versus n

Derivation

  1. Initial program 0.0

    \[\frac{-\left(f + n\right)}{f - n}\]
  2. Using strategy rm

  3. Applied add-cube-cbrt 0.1

    \[\leadsto \color{blue}{{\left(\sqrt[3]{\frac{-\left(f + n\right)}{f - n}}\right)}^3}\]
  4. Removed slow pow expressions
