Perfect Square Number in MATLAB

Perfect Square number:

In mathematics, a square number or perfect square is an integer that is the square of an integer.
Example :25(square of 5) , 36(square of 6) etc.

Algorithm to check perfect number:

Step 1:

Square root the number

Step 2:

Now you have to check whether that number is integer or decimal.


To do so , take ceil or round operation & check that the square root number & the number after performing ceil/round operation on the square root number are same or not.

Step 3:

If both are same , then " YES, the number is perfect square" or else "No , the number is not perfect square number".

MATLAB code:

x=input('Enter the number:');


y=sqrt(x);


z=ceil(y);


if(z==y)


disp('Yes, the number is perfect square number');


else


disp('No , the number is not a perfect square number');


end

Explanation of the code:

You can use same algorithm in JAVA also , just syntax will

differ.

Java Program:

import java.util.Scanner;


import java.lang.Math;


class Perfect


{


public static void main(String args[])


{


Scanner obj=new Scanner(System.in);


System.out.println("Enter the number:");


int m=obj.nextInt();


double z=Math.sqrt(m);


double y=Math.ceil(z);


if(y==z)


{


System.out.println("YES, the number is perfect square

number");


}


else


{


System.out.println("No, the number is not a perfect square number");


}


}
