[Numpy-discussion] problem with float64's str()

Hi,
I seem to have problem with floating point printing with the latest numpy,
python 2.5.2, gcc 4.1.4, and 64-bit linux:
In [24]: print str(0.0012)
0.0012
In [25]: a = numpy.array([0.0012])
In [26]: print str(a[0])
0.0011999999999999999
In [27]: print numpy.__version__
1.0.5.dev4950
It seems like the str() behavior for float64 in the latest numpy's behavior
is different than Python's default behavior (and previous numpy's
behavior).
As I have numerous doc tests, this seems to make many of them failed.
Should the float64's str() behavior be consistent with what's described in
http://docs.python.org/tut/node16.html? Is there any way to get around it
so I can get to the default Python behavior?
Thanks!
Will
