Time: 825.0ms

Precision: binary64

Math

\[\frac{\log x}{\sqrt{x}}\]

↓

\[\frac{\log x}{\sqrt{x}}\]

C

double code(double x) {
	return ((double) (((double) log(x)) / ((double) sqrt(x))));
}

↓

double code(double x) {
	return ((double) (((double) log(x)) / ((double) sqrt(x))));
}

Error

Bits error versus x

Derivation

1. Initial program 0.4

   \[\frac{\log x}{\sqrt{x}}\]

2. Final simplification 0.4

   \[\leadsto \frac{\log x}{\sqrt{x}}\]
