Examples

The query in the following example returns the logarithm base e of the value 0.5:

result, err := client.Query(
	f.Ln(0.5))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
-0.6931471805599453
client.query(
  q.Ln(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
-0.6931471805599453
result = client.query(
  q.ln(0.5)
)
print(result)
-0.6931471805599453
Ln(0.5)
