# Swift Double remainder()

In this tutorial, we will learn about the Swift Double remainder() method with the help of examples.

The `remainder()` method computes the floating-point remainder of numerator/denominator.

### Example

``````// compute the remainder
var result = 10.remainder(dividingBy: 3)

print(result)

// Output: 1.0
``````

## remainder() Syntax

The syntax of the `remainder()` method is:

``num.remainder(dividingBy: otherNumber)``

Here, `num` is a numerator.

## remainder() Parameters

The `remainder()` method takes one parameter

• `otherNumber` - the dividing value (denominator)

## remainder() Return Values

The `remainder()` method returns the floating-point remainder of num/otherNumber.

## Example: Swift Double remainder()

``````// compute the remainder
var result1 = 7.5.remainder(dividingBy: 2.0)
print("Remainder of 7.5/2.0 = ", result1)

var result2 = -17.50.remainder(dividingBy: 2.0)
print("Remainder of -17.50/2.0 = ", result2)

var result3 = 10.remainder(dividingBy: 0)
print("Remainder of 10/0 = ", result3)``````

Output

```Remainder of 7.5/2.1 =  -0.5
Remainder of -17.50/2.0 =  0.5
Remainder of 10/0 =  -nan```

Here, we have used the `remainder()` method to compute the remainder while the numerator is divided by the denominator.
