Time: 929.0ms

Precision: binary64

Math

\[\log \left(x - y\right)\]

↓

\[\log \left(x - y\right)\]

C

double code(double x, double y) {
	return ((double) log(((double) (x - y))));
}

↓

double code(double x, double y) {
	return ((double) log(((double) (x - y))));
}

Error

Bits error versus x

Bits error versus y

Derivation

1. Initial program 0.0

   \[\log \left(x - y\right)\]

2. Final simplification 0.0

   \[\leadsto \log \left(x - y\right)\]
