Create BigInteger via long type variable in Java
BigInteger class is used for big integer calculations which are outside the limit of the primitive data types. It provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.
Firstly, set a long value −
Long l = 198L;
Now, create a new object for BigInteger and pass the above value −
BigInteger bInteger = new BigInteger(l);
The following is an example −
Example
import java.math.BigInteger;
public class Demo {
public static void main(String[] argv) throws Exception {
Long l = 198L;
BigInteger bInteger = BigInteger.valueOf(l);
System.out.println(bInteger);
}
}Output
198
