Java: How to square a number

  1. 1) Square a number by multiplying it by itself. This is how you square a number by multiplying it by itself: int i = 2; int square = i * i;
  2. 2) Square a number with the Math. pow method.
  3. More power multipliers. In general I just multiply the number by itself to get the squared value, but the advantage of the Math.

What is NaN in Java?

In Java, ” NaN ” stands for “not a number” and signifies that a value is not defined. ” NaN ” is not an exception error, but a value that is assigned. For example, imaginary numbers like the square root of negative numbers or zero divided by zero will both print ” NaN ” as the result. Take a look at the example below.

How do you square a number?

How do you manually calculate square roots?

Take the number you wish to find the square root of, and group the digits in pairs starting from the right end. For example, if you want to calculate the square root of 8254129, write it as 8 25 41 29. Then, put a bar over it as when doing long division.

How do you find the square root of a number without using inbuilt functions?

Given a number N, the task is to find the square root of N without using sqrt () function. Find mid of i – 1 and i and compare mid * mid with n, with precision upto 5 decimal places.

  1. If mid * mid = n then return mid.
  2. If mid * mid < n then recur for the second half.
  3. If mid * mid > n then recur for the first half.
