weirdness between windows and linux

a m8 of mine was reading thru the python tutorial and while he was trying out some float numbers formatting, he came to a weird result (note: he is using windowsXP):

>>> print '%0.50f' % (22.0/7.0)
3.14285714285714280000000000000000000000000000000000

this is what i get on linux:

>>> print '%0.50f' % (22.0/7.0)
3.14285714285714279370154144999105483293533325195312

how the hell is this possible?

cos windowze sucks....

Read that, and you'll have either an understanding or a better idea; if the latter, and you're still interested, do some more research.
