Best answer: How do you find the square root in Java?

How do you take the square root in Java?

Java sqrt() method with Examples

Math. sqrt() returns the square root of a value of type double passed to it as argument. If the argument is NaN or negative, then the result is NaN. If the argument is positive infinity, then the result is positive infinity.

How do you calculate squared 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.

What is math floor in Java?

Math. floor() returns the double value that is less 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.

What is NaN in Java?

“NaN” stands for “not a number”. “Nan” is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Finding out the square root of a negative number too is undefined.

What is double in Java?

Java double is used to represent floating-point numbers. It uses 64 bits to store a variable value and has a range greater than float type.

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.
