|
This Java tip illustrates a method of operating with big integer values in code.
Developer may use this in applications which require big calculations and may be
operating on big integer values.
// Create via a string
BigInteger bi1 = new BigInteger("1234567890123456890");
// Create via a long
BigInteger bi2 = BigInteger.valueOf(123L);
bi1 = bi1.add(bi2);
bi1 = bi1.multiply(bi2);
bi1 = bi1.subtract(bi2);
bi1 = bi1.divide(bi2);
bi1 = bi1.negate();
int exponent = 2;
bi1 = bi1.pow(exponent);
