Example

In the following code shows how to use BigInteger.signum() method.

//w w w  . j av a 2 s. c o  m
import java.math.BigInteger;

public class Main {

  public static void main(String[] args) {

    BigInteger bi1 = new BigInteger("0");
    BigInteger bi2 = new BigInteger("10");
    BigInteger bi3 = new BigInteger("-10");

    // assign signum results of bi1, bi2, bi3 to i1, i2, i3
    int i1 = bi1.signum();
    int i2 = bi2.signum();
    int i3 = bi3.signum();

    // print i1, i2, i3 values
    System.out.println(i1);
    System.out.println(i2);
    System.out.println(i3);
  }
}

The code above generates the following result.
