Examples

The following query returns the result of subtracting 10 from 100:

client.query(
  q.Subtract(100, 10)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))

result = client.query(
  q.subtract(100, 10)
)
print(result)
90
result, err := client.Query(
	f.Subtract(100, 10))

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

try
{
    Value result = await client.Query(
        Subtract(100, 10)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
