Usage

From source file:BigNumApp.java

public static void main(String args[]) {
    BigInteger n = new BigInteger("1000000000000");
    BigInteger one = new BigInteger("1");
    while (!n.isProbablePrime(7))
        n = n.add(one);
    System.out.println(n.toString(10) + " is probably prime.");
    System.out.println("It is " + n.bitLength() + " bits in length.");
}

From source file:Main.java

public static void main(String[] args) {

    System.out.println("numberA = " + numberA);

    numberA = numberA.multiply(numberB);
    System.out.println("numberA = " + numberA);

    numberA = numberA.subtract(numberB);
