 =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.
+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

+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.
