Matthew Turk:

This script works for float64, but fails for float32.

```
#!python
from yt.units import cm
from yt.data_objects.octree_subset import YTPositionArray
import numpy as np

a = np.random.random(100).astype("float32") * cm
a *= np.finfo(a.dtype).eps

b = YTPositionArray(np.random.random((100, 3)).astype("float32"), input_units="cm")
print type(b)
b *= np.finfo(b.dtype).eps
```

It's also at paste 4674.
