You'd love perl then - it has 1ulp discrepancies all over the place ;-)
As an added bonus, you can get quite a few 2ulp discrepancies - and I think 
I've seen the odd 3ulp discrepancy there.
This was what sent me down the path of seeing what strtod (which perl does 
*not* use in assigning its floating-point values) was reporting in the first 
place.
