(+ (pow x (- 1)) (pow y (- 1)))

Average Error: 0.0 → 0.0

Time: 990.0ms

Precision: binary64

Math

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

↓

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

Error

Bits error versus x

Bits error versus y

Derivation

1. Initial program 0.0

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

2. Final simplification 0.0

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