Kotlin Multiplication

Kotlin Multiplication Operator

Kotlin Multiplication operator returns the product of given left and right operands.

Syntax

The syntax to use Arithmetic Multiplication operator is

``n1 * n2``

where

• `n1` is the left operand
• `*` is the symbol used for Multiplication operator
• `n2` is the right operand

Return Value

The above expression returns the sum of the two given values. The data type of the return value depends on the given values. If given values are of different data types, then the resulting would be the higher data type (data type that can allocate larger memory).

Chaining Multiplication Operator

We can also chain the operator to multiply more than two numbers in a single expression, as shown in the following.

``n1 * n2 * n3 * n4``

You can multiply as many numbers in a single expression as you would like by chaining the Multiplication operator.

Examples

Multiplication of 4 and 6

In the following program, we take two variables: `n1`, and `n2` with the values `4` and `6` respectively; and find their product.

Kotlin Program

``````fun main() {
var n1 = 4
var n2 = 6

val result = n1 * n2
println("n1 = \$n1\nn2 = \$n2\nn1 * n2 = \$result")
}``````

Output

``````n1 = 4
n2 = 6
n1 * n2 = 24``````

Multiplication of more than two numbers in a single expression

In the following program, we take four integer variables: `n1`, `n2`, `n3`, and `n4`, and find the product of the integer values in them.

Kotlin Program

``````fun main() {
var n1 = 4
var n2 = 6
var n3 = 2
var n4 = 7

val result = n1 * n2 * n3 * n4
println("n1 * n2 * n3 * n4 = \$result")
}``````

Output

``n1 * n2 * n3 * n4 = 336``

Multiplication of 3.14 and 2.1

In the following program, we find the product of floating point numbers.

Kotlin Program

``````fun main() {
var n1 = 3.14
var n2 = 2.1

val result = n1 * n2
println("n1 = \$n1\nn2 = \$n2\nn1 * n2 = \$result")
}``````

Output

``````n1 = 3.14
n2 = 2.1
n1 * n2 = 6.594``````
