Question

Use Java programming language

Float calculations:

Initially, declare a float variable and give it the initial value 3.0.

float number = 3.0f;

Now, multiply the number by 10 and print out the value, using default precision as shown.

number *= 10.0;
System.out.println(number);

Repeat this 20 times. ( use a loop. You will find it helpful if you print out both the new value of number and the iteration. So, iteration 1 prints out 30.0; iteration 2 prints out 300.0, etc.)

Answer 1

public class FloatOperations {

    public static void main(String[] args) {
        float number = 3.0f;
        for (int i = 0; i < 20; i++) {
            number *= 10.0;
            System.out.println(number);
        }
    }
}
