Examples

The following query returns the cosine of 0.5:

client.query(
  q.Cos(0.5)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))

0.8775825618903728

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

0.8775825618903728

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

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

try
{
    Value result = await client.Query(
        Cos(0.5)
    );

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

DoubleV(0.8775825618903728)

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