| Utility-class for all arithmetic-operations.<br><br> |
| |
| All operations (+ - / *) return a Number which type is the type of the bigger argument.<br> |
| Example:<br> |
| <code>add ( new Integer(10), new Integer(1))</code> will return an <code>Integer</code>-Object with the value 11<br> |
| <code>add ( new Long(10), new Integer(1))</code> will return an <code>Long</code>-Object with the value 11<br> |
| <code>add ( new Integer(10), new Float(1))</code> will return an <code>Float</code>-Object with the value 11<br><br> |
| |
| Overflow checking:<br> |
| For integral values (byte, short, int) there is an implicit overflow correction (the next "bigger" |
| type will be returned). 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. |
