For example, if you call <code>add (new Integer (Integer.MAX_VALUE), 1)</code> a <code>Long</code>-object will be returned with the correct value of <code>Integer.MAX_VALUE+1</code>.<br> In addition to that the methods <code>multiply</code>,<code>add</code> and <code>substract</code> implement overflow checks for <code>long</code>-values. That means that if an overflow occurs while working with long values a BigInteger will be returned.<br> For all other operations and types (such as Float and Double) there is no overflow checking. <P>
