Examples of java.math.BigInteger.negate()

java.math.BigInteger.negate()
Returns a BigInteger whose value is {@code (-this)}. @return {@code -this}

            // And then, let's just multiply by 10, add a new digit
            I = I.multiply(BigInteger.valueOf(10)).add(BigInteger.valueOf(rnd.nextInt() & 0xF));


            // Plus switch sign every now and then
            if ((i % 3) == 0) {
                I = I.negate();
            }
        }
    }
