BigInteger

The java.math.BigInteger class provides analogues to all of Java's primitive type integer operators. Simply stating, the BigInteger class can be used to deal with very large integers. A BigInteger object can be constructed in multiple ways like:
BigInteger(String val)
BigInteger(String val, int radix)

This code can be used to add two very large integers.


	            BigInteger bi1 = new BigInteger("12334658679567543242343654434");

	            BigInteger bi2 = new BigInteger("30457934659437659435743563745");

	            BigInteger bi3 = bi1.add(bi2);

	            System.out.println(bi3);

It outputs 42792593339005202678087218179 (Try It Yourself!), which is the sum of two large integers i.e. a very large integer.

Using the BigInteger class, we can perform operations on integers having upto 2³¹-1 i.e. 2,147,483,647 digits.

The java. class is used to perform all available and some additional primitive integer operations on very large integers.

BigInteger Methods

Here is a list of some methods provided by the java.math.BigInteger class.

Method	Description
bi1.add(bi2)	Addition of bi1 and bi2
bi1.subtract(bi2)	Subtraction of bi1 and bi2
bi1.multiply(bi2)	Multiplication of bi1 and bi2
bi1.divide(bi2)	Division of bi1 and bi2
bi1.remainder(bi2)	Remainder when bi1 is divided by bi2
bi1.pow(bi2)	bi1 to the power of bi2
bi1.compareTo(bi2)	Comparison of bi1 and bi2
bi1.intValue()	bi1 converted to int
bi1.longValue()	bi1 converted to long
bi1.floatValue()	bi1 converted to float
bi1.doubleValue()	bi1 converted to double
bi1.toString()	bi1 converted to String
bi1.toString(radix)	bi1 of base 'radix' converted to String
bi1.and(bi2)	AND of bi1 and bi2
bi1.or(bi2)	OR of bi1 and bi2
bi1.not()	NOT of bi1
bi1.xor(bi2)	XOR of bi1 and bi2

Here, bi1 and bi2 are two BigInteger objects. Using the BigInteger methods, large values like 50! (Try It Yourself!) can be calculated.

Fill in the Blanks to output the remainder obtained when BigInteger 'bi1' is divided by BigInteger 'bi2'.

System.out.println(bi1.(bi2))
