(- (pow x 2.0) (pow x (- 2.0)))

Average Error: 0.0 → 0.0

Time: 1.5s

Precision: binary64

Math

\[{x}^{2} - {x}^{\left(-2\right)}\]

↓

\[{x}^{2} - {x}^{\left(-2\right)}\]

Error

Bits error versus x

Derivation

1. Initial program 0.0

   \[{x}^{2} - {x}^{\left(-2\right)}\]

2. Final simplification 0.0

   \[\leadsto {x}^{2} - {x}^{\left(-2\right)}\]
