+ * --- A small description of the E1-16/32X FP unit. ---
+ * FP exceptions can be enabled and disabled through
+ * <feenableexcept>, <fedisableexcept>.
+ *
+ * - When an enabled exception takes place a SIGFPE signal
+ * is sent to the process by the exception handler. User
+ * can test for the exception that took place through
+ * <fetestexcept>.
+ * feraiseexcept works only for accrued exceptions.
+ *
+ * - When a disabld exception takes place it does not generate
+ * a trap. The user can check if any exception took place after
+ * an FP instruction by issuing an <fetestexcept> command.
+ * User should first clear the G2 register by issuing an
+ * <feclearexcept> function.
+ * The following program is a typical example of how the user
+ * should check for exceptions that did not generate a SIGFPE
+ * signal :
+ * {
+ * double f;
+ * int raised;
+ * feclearexcept (FE_ALL_EXCEPT);
+ * f = compute ();
+ * raised = fetestexcept (FE_OVERFLOW | FE_INVALID);
+ * if (raised & FE_OVERFLOW) { ... }
