80 bit floating point math

I am doing a test at Digital Corporation. I know that the win16 api
x86 emulator that comes with windows NT 4.0 has problems with "temp real" or
80 bit floating point numbers. I now want to test digital's fx!32 win32 api
x86 emulator's ability to handle these type of numbers.

I figured the best way to do that would be to use Mathematica,

I have discovered the N function but I don't see how I can guarantee myself
that this digit precision mechanism would ever create a 80 bit precison
floating point number.

I printed the MAX(something) variable and after a quick convesion I found out
that it was 2^1024 or another words a long real (63 bit precision).

please reply to moore@ntmail.zso.digital.com as I don't normally frequent this
nesw group.
