Parameters

Argument Type Definition and Requirements

value

Number

Take the ln of this value.

Returns

A Number which is the result of the Ln operation.

Examples

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

try
{
    Value result = await client.Query(
        Ln(0.5)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
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
try {
  println(Await.result(
  client.query(
    Ln(0.5)
  ),
  5.seconds
))} catch {
  case unknown: Throwable => println("Error: " + unknown.getMessage())
}
-0.6931471805599453
