Java Large integer Operation __java

Java Large number Operation Some applications of large Java integers:

import java.util.*;

import java.math.*;

Public class main{

Public static void main (String args[]) {

Scanner cin = new Scanner (system.in);

BigInteger A, B;

End With file EOF

while (Cin.hasnext ()) {

A = Cin.nextbiginteger ();

b = Cin.nextbiginteger ();

System.out.println (A.add (b)); Large integer Addition

System.out.println (A.subtract (b)); Large integer Subtraction

System.out.println (a.multiply (b)); Large integer Multiplication

System.out.println (A.divide (b)); Large integer division (rounding)

System.out.println (A.remainder (b)); Large integer Modulo

Comparison of large integers

if (A.compareto (b) = = 0) System.out.println ("a = = B"); Large integer a==b

else if (A.compareto (b) > 0) System.out.println ("a > B"); Large integer a>b

else if (A.compareto (b) < 0) System.out.println ("a < B"); Large integer a<b

Large integer Absolute value

System.out.println (A.abs ()); Absolute value of large integer A

The power of a large integer

int exponent=10;

System.out.println (A.pow (exponent)); The exponent power of large integer A

Returns a string representation of a large integer decimal

System.out.println (A.tostring ());

Returns a string representation of a large integer P-system

int p=8;

System.out.println (A.tostring (p));

}

}
