<para>This exception policy will trap at compile time any operation
|
|
<emphasis><emphasis role="bold">COULD</emphasis></emphasis> result in a
|
|
runtime exception. It can be used in an environment which can tolerate
|
|
neither arithmetic errors nor runtime overhead. Usage of this policy will
|
|
almost always require altering one's program to avoid exceptions.</para>
