Description

The Ln function returns the natural logarithm (base e) of the operand.

Argument Type Definition and Requirements

Argument	Type	Definition and Requirements
`value`	Number	Take the ln of this value.

value

Number

Take the ln of this value.

A number which is the result of the Ln operation.

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

Value result = await client.Query(
    Ln(0.5)
);
Console.WriteLine(result);

DoubleV(-0.6931471805599453)

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

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}

-0.6931471805599453

System.out.println(
    client.query(
        Ln(Value(0.5))
    ).get());

-0.6931471805599453

client.query(
  q.Ln(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))

-0.6931471805599453

result = client.query(
  q.ln(0.5)
)
print(result)

-0.6931471805599453

println(Await.result(
  client.query(
    Ln(0.5)
  ),
  5.seconds
))
