You make sure the result of your division is a Float (Ah, how I long for
the "new division" to be standard!) and you use %f instead of %d

#!/usr/bin/env python


def ShowSize(raw):
    if raw < 3000:
        return "%db" % raw
    elif raw < 2000000:
        return "%.2fkb" % (raw / 1000.)
    elif raw < 2000000000L:
        return "%.2fMb" % (raw / 1000000.)
    else:
        return "%.2fGb" % (raw / 1000000000.)


print ShowSize(2567L)
print ShowSize(2567000L)
print ShowSize(256700000L)
print ShowSize(2567000000L)
print ShowSize(256700000000L)

And here are the results:

>>> execfile("junk.py")
2567b
2.57M
256.70M
2.57G
256.70G
