Average Error: 23.1 → 23.1

Time: 948.0ms

Precision: binary64

Math

\[\frac{-1}{\left(-t\right) + \sqrt{1 + t \cdot t}}\]

↓

\[\frac{-1}{\left(-t\right) + \sqrt{1 + t \cdot t}}\]

Error

Bits error versus t

Derivation

1. Initial program 23.1

   \[\frac{-1}{\left(-t\right) + \sqrt{1 + t \cdot t}}\]

2. Final simplification 23.1

   \[\leadsto \frac{-1}{\left(-t\right) + \sqrt{1 + t \cdot t}}\]
