Ridge 3200 Floating Point Underflow Bug

[Bruce P Johnston]

Has anyone experienced floating point underflow problems on
a Ridge 3200 system?

We are having problems working with very small numbers near
the lower limit of double precision (ie ~1.0d-308).  Instead of 
underflowing to zero (0.0) as they should, underflowed numbers
"wrap around" to very large numbers (~1.0d+308).

I would appreciate hearing from anyone who has experienced this
and might have a fix (other than scaling or software checks) for
this problem.
