## What is BigInteger in Java?

BigInteger provides analogues to all of Java’s primitive integer operators, and all relevant methods from java. lang. Math. Additionally, BigInteger provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.

**How do you take power of BigInteger?**

math. BigInteger. pow(int exponent) method is used to calculate a BigInteger raise to the power of some other number passed as exponent whose value is equal to (this)exponent. This method performs operation upon the current BigInteger by which this method is called and exponent passed as parameter.

**How do you make a BigInteger modulo?**

BigInteger. mod(BigInteger m) returns a BigInteger whose value is (this mod m). This method differs from remainder in that it always returns a non-negative BigInteger.

### How do you convert Bigint to double?

math. BigInteger. doubleValue() converts this BigInteger to a double value. If the value return by this function is too big for a magnitude to represent as a double then it will be converted to Double.

### How do I create an array of BigInteger in Java?

BigInteger class provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations. BigInteger bInteger = new BigInteger(arr); The following is an example that creates BigInteger from a byte array in Java.

**How does BigInteger modPow work?**

BigInteger modPow() Method in Java modPow() method returns a BigInteger whose value is (thisexponent mod m ). If exponent == 1, the returned value is (this mod m) and if exponent < 0, the returned value is the modular multiplicative inverse of (this-exponent). The method throws an ArithmeticException if m <= 0.

**How do you use BigInteger equals in Java?**

math. BigInteger. equals(Object x) method compares this BigInteger with the object passed as the parameter and returns true in both are equal in value else it returns false. Parameter: This method accepts a single mandatory parameter x which is the Object to which BigInteger Object is to be compared.

#### What is the range of BigInteger in Java?

BigInteger must support values in the range -2 Integer.MAX_VALUE (exclusive) to +2 Integer.MAX_VALUE (exclusive) and may support values outside of that range. The range of probable prime values is limited and may be less than the full supported positive range of BigInteger . The range must be at least 1 to 2500000000.

#### What is the max value of BigInteger in Java?

The largest primitive data type that can store integer values in Java is the 64-bit long. Given that it is a signed data type, this gives it the range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. So we already established that BigIntegers are “Big”.

**What is BigInteger sqrt () method in Java?**

BigInteger sqrt () Method in Java Last Updated : 24 May, 2019 java.math.BigInteger.byteValueExact () is an inbuilt function added in Java SE 9 & JDK 9 which returns BigInteger value of square root of a BigInteger on which sqrt () methhod is applied.

**How to convert a BigInteger to a double in Java?**

BigInteger [] divideAndRemainder (BigInteger val): This method returns an array of two BigIntegers containing (this / val) followed by (this % val). double doubleValue (): This method converts this BigInteger to a double.

## How to get square root of 122 Using BigInteger?

Input: 234876543456 Output: 484640 Explanation: 122 is given as input which is the bigInteger. The square root of 122 is 11.04536 whose BigInteger equivalent is 11 and using sqrt () method of BigInteger class we can get Square root of any BigInteger.

## What is BigInteger class in Java?

BigInteger Class in Java Difficulty Level : Medium Last Updated : 20 May, 2019 BigInteger class is used for mathematical operation which involves very big integer calculations that are outside the limit of all available primitive data types.
