Operations may return PlusSignalingNaN or PlusQuietNaN

When running on HP-UX, mathematical operations that return NaNs may return
different flavors, depending on the specific OS version and chipset.  For
example,
  (5.0 / 0) * 0 * 1 may return PlusSignalingNaN or PlusQuietNaN

Workaround

These return values are provided by the operating system, outside of GemStone's
control.  Ensure your application can handle the OS results, and verify
before moving to new OS systems or versions.
