-=head2 Handling of underflow and overflow
-
-Prior to VOS Release 14.7.0, VOS does not support automatically
-mapping overflowed floating-point values to +infinity, nor
-automatically mapping underflowed floating-point values to zero,
-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.
-
-As of VOS Release 14.7.0, the VOS POSIX runtime sets up the
-PA-RISC hardware floating-point status register so that the
-overflow and underflow exceptions do not trap, but instead
-automatically convert the result to infinity or zero, as
-appropriate. As of this writing, there are still floating-point
-operations that can trap, for example, subtracting two infinite
-values. This is recorded as suggestion posix-1022, which is not
-yet fixed.
