+=head2 Handling of underflow and overflow
+
+VOS does not support automatically mapping overflowed
+floating-point values to +infinity, nor automatically mapping
+underflowed floating-point values to -infinity, unlike many
+other platforms.  The Perl pack function has been modified to
+perform such mapping in software on VOS.  Performing other
+floating-point computations that underflow or overflow will
+probably result in SIGFPE.  Don't push your luck.
+
+=head1 TEST STATUS
+
+When Perl is built using the native build process on VOS Release
+14.5.0 and GNU C++/GNU Tools 2.0.1, all attempted tests either
+pass or result in TODO (ignored) failures.
