Re: [Python-Dev] Why don't range and xrange threat floats as floats?

Why don't range and xrange threat floats as floats?
Is there any good reason range and xrange don't threat floats as floats but
as integers?
When I enter float arguments in a range, the floats are treated as integers.
(+ some warning)

This is how I think it should work:

>>>>range(0, 1, 0.1)

[0.0, 0.10000000000000001, 0.20000000000000001, 0.29999999999999999,
0.40000000000000002, 0.5, 0.59999999999999998, 0.69999999999999996,
0.80000000000000004, 0.90000000000000002]

I got these results by:

>>>>[x/10. for x in xrange(10)]

I'm not looking for alternatives, just for the reason that it works this
way.

Hi,

I don't think the Python developers list is th best list to post this
kind of question.

What version of Python did you use for this test?
