The compiled calculator gives strange results:
0>> 1/2.0-1/3
5.46834151467e-304
// Time 0
1>> 1/2.0
3.64556100978e-304
// Time 0
2>> 1/3
1/3
// Time 0
3>> 1/1.
3.64556100978e-304
// Time 0
4>> 1.
3.64556100978e-304
// Time 0

The last example shows that it's not just a computation problem.

There's something extremely fishy on that box!
