I tried your code and it failed for me -- the 'y'
case came out "non-NaN"

Have you tried:
    if unknown >= 1e255 then
       puts( 1, "it's a NaN!")
    ....

Works under the interpreter but I haven't tried the compiler
The '1e255' comes directly from the IEEE 754 NaN definition,
so it should be o.k.

The test probably should be:
    if unknown >= 1e255 or unknown <= -1e255 then
