FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

`Divide`

This reference topic applies to FQL v4. Go to this page for the latest FQL v10 reference topics.

Divide( value_1, value_2, ... )

divide( value_1, value_2, ... )

Divide( value_1, value_2, ... )

Divide( value_1, value_2, ... )

Divide( value_1, value_2, ... )

Divide( value_1, value_2, ... )

Description

The Divide function computes the quotient of two or more numbers. When all of the numbers are integers, the result is a Long integer value. When any of the numbers is a floating-point number, the result is a Double-precision, floating-point value.

Attempting to Divide an empty list results in an "invalid argument" error.

Attempting to Divide any value by zero results in a "invalid argument" error.

Parameters

Parameter Type Definition and Requirements

Parameter	Type	Definition and Requirements
`value`	Number	Two or more Numbers to divide.

value

Number

Two or more Numbers to divide.

Returns

A Number which is the result of dividing two or more numbers. When all of the parameters are integers, the result is a Long (integer division). Otherwise, the result is a Double (floating-point division).

Examples

The following query executes two equivalent division operations. The first example provides the Divide function a list of numbers. The second equivalent operation first divides 10 by 5, the takes the result of that operation and divides it by 2:

client.query(
  q.Divide(10, 5, 2)
)
.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.divide(10, 5, 2)
)
print(result)

result, err := client.Query(
	f.Divide(10, 5, 2))

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

try
{
    Value result = await client.Query(
        Divide(10, 5, 2)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

LongV(1)

System.out.println(
    client.query(
        Divide(Value(10), Value(5), Value(2))
    ).get());

Divide(10, 5, 2)

bytesOut: 14

is equivalent to:

client.query(
  q.Divide(q.Divide(10, 5), 2)
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,

))

result = client.query(
    q.divide(q.divide(10, 5), 2)
)
print(result)

result, err := client.Query(
	f.Divide(f.Divide(10, 5), 2))

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

try
{
    Value result = await client.Query(
        Divide(Divide(10, 5), 2)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

LongV(1)

System.out.println(
    client.query(
        Divide(Divide(Value(10), Value(5)), Value(2))
    ).get());

The following query demonstrates that dividing with integers results in an integer result:

client.query(
  q.Divide(1, 2)
)
.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.divide(1, 2)
)
print(result)

result, err := client.Query(
	f.Divide(1, 2))

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

try
{
    Value result = await client.Query(
        Divide(1, 2)
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

LongV(0)

System.out.println(
    client.query(
        Divide(Value(1), Value(2))
    ).get());

Divide(1, 2)

The following query demonstrates that dividing with a double value results in a floating-point result:

client.query(
  q.Divide(1, q.ToDouble(2))
)
.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.divide(1, q.to_double(2))

print(result)

result, err := client.Query(

if err != nil {

}

try
{

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