(pow x (/ (- 1) y))

Average Error: 0.0 → 0.0

Time: 2.5s

Precision: binary64

Math

\[{x}^{\left(\frac{-1}{y}\right)}\]

↓

\[{x}^{\left(\frac{-1}{y}\right)}\]

Error

Bits error versus x

Bits error versus y

Derivation

1. Initial program 0.0

   \[{x}^{\left(\frac{-1}{y}\right)}\]

2. Final simplification 0.0

   \[\leadsto {x}^{\left(\frac{-1}{y}\right)}\]
