Kotlin Program to Multiply Two Floating-Point Numbers

In this article, we will understand how to multiply two floating-point numbers. A floating-point number, is a positive or negative whole number with a decimal point. There are two types of floating point in Kotlin

• Float
• Double

Below is a demonstration of the same ?

Suppose our input is

val1: 10.5 val2: 45.0 

The desired output would be

The product is: 472.5 

Algorithm

• Step 1 ? Start

• Step 2 ? Declare three floating points: val1, val2 and product

• Step 3 ? Define the floating-point values

• Step 4 ? Read the values

• Step 5 ? Multiply the two values using a multiplication operator (*)

• Step 6 ? Display the result

• Step 7 ? Stop

Example 1

In this example, we will multiply two floating-point numbers using the multiplication arithmetic operator

 fun main() { val val1 = 10.5f val val2 = 45.0f println("The first value is defined as: $val1") println("The second value is defined as: $val2") val product = val1 * val2 println("The product is: $product") } 
 
 
 

Output

The first value is defined as: 10.5 The second value is defined as: 45.0 The product is: 472.5 

Example 2

In this example, we will multiply two floating-point numbers:

 fun product(val1 : Float, val2 : Float){ val product = val1 * val2 println("The product is: $product") } fun main() { val val1 = 12.5f val val2 = 40.0f println("The first value is defined as: $val1") println("The second value is defined as: $val2") product(val1, val2) } 
 
 
 

Output

The first value is defined as: 12.5 The second value is defined as: 40.0 The product is: 500.0 

Example 3

In this example, we will multiply two floating-point numbers (Double) using the multiplication arithmetic operator

 fun main() { val val1 = 12.0 val val2 = 23.5 println("The first value is defined as: $val1") println("The second value is defined as: $val2") val product = val1 * val2 println("
The product is: $product") } 
 
 
 

Output

The first value is defined as: 12.0 The second value is defined as: 23.5 The product is: 282.0
