## How do you do to the power of in Java?

**The java.** **lang.** **Math.** **pow() is used to calculate a number raise to the power of some other number.**

- If the second parameter is positive or negative zero then the result will be 1.0.
- If the second parameter is 1.0 then the result will be same as that of the first parameter.

## Can you use powers in Java?

Power function in Java is **used to calculate a number raised to the power of some other number**. This function accepts two parameters and returns the value of the first parameter raised to the second parameter. … Examples of Power function.

## How do you power an int in Java?

Use Math.

We can easily calculate the power of an integer with the function Math. **pow()** provided by the Java library. The number raised to the power of some other number can be calculated using this function. This method takes two parameters; the first number is the base while the second is the exponent.

## What is XOR in Java?

JavaObject Oriented ProgrammingProgramming. Bitwise XOR (**exclusive or**) “^” is an operator in Java that provides the answer ‘1’ if both of the bits in its operands are different, if both of the bits are same then the XOR operator gives the result ‘0’. XOR is a binary operator that is evaluated from left to right.

## 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 the E in Java?

exp() method. The java. lang. … exp() is used to return the Euler’s number e raised to the power of a double value. Here, e is an Euler’s number and it is approximately equal to **2.718281828459045**.

## How do you write 10 to the power 9 in Java?

Since 10^{9} fits into an int and is also exactly representable as a double , you can do this: int exp = (int) Math. pow(10, 9); BigInteger answer = **BigInteger**.

## What is arrays in Java?

An array in Java is **a set of variables referenced by using a single variable name combined with an index number**. Each item of an array is an element. All the elements in an array must be of the same type. … An int array can contain int values, for example, and a String array can contain strings.

## What is the power of a number?

A power is **the product of multiplying a number by itself**. Usually, a power is represented with a base number and an exponent. The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied.

## What is long in Java?

The long is **a numeric data type in Java**. This is also the primitive type. The long type takes 64 bits of memory. The maximum value that a long type variable can store is 9,223,372,036,854,775,807L. The minimum value is -9,223,372,036,854,775,808L.

## How do you square 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.
