In this article, we will understand how to multiply two floating-point numbers. Floating point numbers are numbers with decimal values. Float data type is a single-precision 32-bit IEEE 754 floating point. It is mainly used to save memory in large arrays of floating-point numbers. The Default value is 0.0f. Float data type is never used for precise values such as currency.
Below is a demonstration of the same −
Input
Suppose our input is −
Value_1: 12.4f Value_2: 15.7f
Output
The desired output would be −
Result : 194.68f
Algorithm
Step 1- Start Step 2- Declare three floating points: input_1, input_2 and product Step 3- Prompt the user to enter two floating point value/ 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
Here, the input is being entered by the user based on a prompt. You can try this example live in ourcoding ground tool .
import java.util.Scanner; public class MultiplyFloatValues{ public static void main(String[] args){ float input_1, input_2, my_prod; Scanner my_scan = new Scanner(System.in); System.out.println("A reader object has been defined "); System.out.println("Enter the first floating point number: "); input_1 = my_scan.nextFloat(); System.out.println("Enter the second floating point number: "); input_2 = my_scan.nextFloat(); my_prod = input_1 * input_2; System.out.println("\nThe product of the two values is: " + my_prod); } }
Output
A reader object has been defined Enter the first floating point number: 12.4 Enter the second floating point number: 15.7 The product of the two values is: 194.68
Example 2
Here, the integer has been previously defined, and its value is accessed and displayed on the console
public class MultiplyFloatValues{ public static void main(String[] args){ float value_1, value_2, my_prod; value_1 = 12.4f; value_2 = 15.7f; System.out.printf("The two numbers are %.2f and %.2f ",value_1, value_2 ); my_prod = value_1 * value_2; System.out.println("\nThe product of the two values are: " + my_prod); } }
Output
The two numbers are 12.40 and 15.70 The product of the two values are: 194.68
