1. If parameter x is positive double value, this method will return the square root of x.
2. When x is NaN or less than zero, this method will return NaN.

## How do you square a number in Java?

Squaring a number in Java can be accomplished in two ways. One is by multiplying the number by itself. The other is by using the Math. pow() function, which takes two parameters: the number being modified and the power by which you’re raising it.

## Why is i the square root of negative one?

Here, the term “imaginary” is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

## What is the formula of the square root?

The square root formula is used to find the square root of a number. We know the exponent formula: n√x x n = x1/n. When n= 2, we call it square root. We can use any of the above methods for finding the square root, such as prime factorization, long division, and so on.

## What does math floor do in Java?

The java. lang. Math. floor() returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer.

## How many types of error are there in Java?

There are three kinds of errors: syntax errors, runtime errors, and logic errors. These are errors where the compiler finds something wrong with your program, and you can’t even try to execute it.

## How do you find the power of a number in Java?

Steps to Find Power of a Number

1. Read or initialize base and exponent.
2. Take another variable ( power ) to store the result and initialize it to 1.
3. Using the for loop or while loop, multiply the base by power and store the result into power.
4. Repeat the above step (3) until the exponent becomes 0.
5. Print the result.

## How do you Ceil a number in Java?

ceil () returns the double value that is greater than or equal to the argument and is equal to the nearest mathematical integer. Note: If the argument is Integer, then the result is Integer. If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.

## How do you solve 100 factorial?

Factorial of 100 has 158 digits. factorial(n)

1. Create an array ‘res[]’ of MAX size where MAX is number of maximum digits in output.
2. Initialize value stored in ‘res[]’ as 1 and initialize ‘res_size’ (size of ‘res[]’) as 1.
3. Do following for all numbers from x = 2 to n.

## What is the purpose of sqrt number?

The SQRT function is one of the math and trigonometry functions. It is used to return the square root of a number. where x is a numeric value entered manually or included into the cell you make reference to. Note: if the x value is negative, the function returns the #NUM!

## How does sqrt function work?

SQRT is similar to the POWER function. However, the POWER function works like an exponent in a standard math equation. For example, for the number 25, we will provide the formula =SQRT(25) and =POWER( 25, 1/2).
