[Vm-dev] FFI Testing - Curiouser and curiouser!

[Andres Valloud]

Something doesn't look right there.  The test in question appears to be 
adding all integers from 1 to 9 as floating point numbers, and seems to 
be expecting the result is 45 as a floating point number.  That 
calculation should need no epsilons, it's lossless in floating point 
land (under the usual assumptions).  What's going on, exactly?
