Average Error: 0.0 → 0.0

Time: 4.5s

Precision: binary64

Math

\[{x}^{8} - {x}^{\left(-8\right)}\]

↓

\[{x}^{8} - {x}^{\left(-8\right)}\]

Error

Bits error versus x

Derivation

1. Initial program 0.0

   \[{x}^{8} - {x}^{\left(-8\right)}\]

2. Final simplification 0.0

   \[\leadsto {x}^{8} - {x}^{\left(-8\right)}\]
