Swift Arithmetic Operators

Arithmetic Operators in Swift

Arithmetic Operators are used to perform basic mathematical arithmetic operators like addition, subtraction, multiplication, etc.

The following table lists out all the arithmetic operators in Swift.

Operator Symbol	Name	Example	Description
+	Addition	x + y	Returns the sum of values in x and y.
-	Subtraction	x - y	Returns the subtraction y from x.
*	Multiplication	x * y	Returns the product of values in x and y.
/	Division	x / y	Returns the quotient in the division of x by y.
%	Modulus	x % y	Returns the remainder in the division of x by y.

Arithmetic Operators

1. Addition

Addition operator takes two numeric values as inputs: x and y, and returns the result of their sum.

main.swift

var x = 5
var y = 2
var result = x + y
print("\(x) + \(y) is \(result)")

Output

5 + 2 is 7

2. Subtraction

Subtraction operator takes two numeric values as inputs: x and y, and returns the difference of right operand y from the left operand x.

main.swift

var x = 5
var y = 2
var result = x - y
print("\(x) - \(y) is \(result)")

Output

5 - 2 is 3

3. Multiplication

Multiplication operator takes two numeric values as inputs, and returns the result of their product.

main.swift

var x = 5
var y = 2
var result = x * y
print("\(x) * \(y) is \(result)")

Output

5 * 2 is 10

4. Division

Division operator takes two numeric values as inputs: x and y, and returns the quotient of the division of the left operand x by the right operand y.

If x and y are integers, then the division operator performs integer division, and returns an integer quotient value.

main.swift

var x = 5
var y = 2
var result = x / y
print("\(x) / \(y) is \(result)")

Output

5 / 2 is 2

If x and y are floating point numbers, then the division operator performs floating point division, and returns a floating point quotient value.

main.swift

var x: Float = 5.0
var y: Float = 2
var result = x / y
print("\(x) / \(y) is \(result)")

Output

5.0 / 2.0 is 2.5

5. Modulo

Division operator takes two numeric values as inputs: x and y, and returns the remainder of the division of the left operand x by the right operand y.

Modulo operator can be used with integer values only.

main.swift

var x = 5
var y = 2
var result = x % y
print("\(x) % \(y) is \(result)")

Output

5 % 2 is 1
