 * The *div0 functions:
 * - Return the value passed to them as a parameter
 * - Or, return a fixed value defined by the execution environment (such as 0)
 * - Or, raise a signal (often SIGFPE) or throw an exception, and do not return
 *
 * An application may provide its own implementations of the *div0 functions to
 * for a particular behaviour from the *div and *divmod functions called out of
