2.14 LAB: Using math functions Given three floating-point numbers x, y, and z, output the square root of x, the absolute value of (y minus z) , and the factorial of (the ceiling of z).

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:

print('%0.2f %0.2f %0.2f' % (your_value1, your_value2, your_value3))

Ex: If the input is:

5.0

6.5

3.2

Then the output is:

2.24 3.30 24.00

In Java:

import java.util.Scanner;

import java.lang.Math;

public class MyClass {

   public static void main(String args[]) {

     Scanner input = new Scanner(System.in);

     float x, y, z;

     System.out.print("Enter three numbers: ");

     x = input.nextFloat();      y = input.nextFloat();      z = input.nextFloat();

     System.out.print("Square root of x: ");

     System.out.printf("%.2f",Math.sqrt(x));

     System.out.println();

     System.out.print("Absolute of y - z: ");

     System.out.printf("%.2f",Math.abs(y - z));

     System.out.println();

int fact = 1;

     for(int i = 1;i<=(int)Math.ceil(z);i++){

         fact*=i;

     }

     System.out.print("Factorial of z: "+fact);    

   }

}

Explanation:

This line declares x, y and z as float

     float x, y, z;

This line prompts user for three numbers

     System.out.print("Enter three numbers: ");

The next line get input for x, y and z

     x = input.nextFloat();      y = input.nextFloat();      z = input.nextFloat();

The italicized prints the square root of x rounded to 2 decimal places

     System.out.print("Square root of x: ");

     System.out.printf("%.2f",Math.sqrt(x));

     System.out.println();

The italicized prints the absolute of y - z to 2 decimal places      

     System.out.print("Absolute of y - z: ");

     System.out.printf("%.2f",Math.abs(y - z));

     System.out.println();

This initializes fact to 1

int fact = 1;

The following iteration calculates the factorial of ceil z

     for(int i = 1;i<=(int)Math.ceil(z);i++){

         fact*=i;

     }

     This prints the calculated factorial

     System.out.print("Factorial of z: "+fact);    

   }

}

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
