Hi, I have the following functions, but ' dx = abs(i2 - i1)/min(i2,
i1)' always return 0, can you please tell me how can i convert it from
an integer to float?
def compareValue(n1, n2):
i1 = int(n1)
i2 = int(n2)
dx = abs(i2 - i1)/min(i2, i1)
print dx
return dx < 0.05 10 107645

When two integers are involved in a division, the result will also be a
division. If one of the operands is a float, then the result will be a
float instead. So try casting one of the values to a float before
performing the division:
dx = float(abs(i2 - i1))/min(i2, i1)

My bad, I meant the result will also be an *integer*

yinglcs, you can use float() or the new division:
>>1 / 2
0
>>1 / float(2)
0.5
>>from __future__ import division 1 / 2
0.5

Or you could just put "from __future__ import division" at the top of
your file.
see http://www.python.org/dev/peps/pep-0238/ for details.

You could also prepend
from __future__ import division

How, um, perlesque.
I rather think that this is a bit more pythonic:
x = float(x)

How did the new division ever get approved?!
By being introduced as a PEP, which is now numbered PEP 238.
<URL:http://www.python.org/dev/peps/pep-0238/>
That's not pythonic! What if you then need to divide two integers
and find an element in a list or dict?
Then your code is dependent on ambiguous behaviour which has changed
in newer Python versions.
As described in the above document, the '//' operator will
unambiguously request floor division, even in older versions of
Python.
I know that at the moment it is not implemented unless imported from
__future__, but I expect that it eventually might be.
Please read PEP 238 to see the implementation plan.
That would be a problem with backwards compatibility.
The older Python versions aren't going away. Anyone who wants their
old code to work with new versions of Python has a responsibility to
see what parts of their code need to be updated.

I don't think that's what you really want to do.
What you really want is for dx to be a float rather than being truncated to
an integer. Division is going to behave that way in the future, so if you
want it to behave that way now, you can write
from __future__ import division
at the beginning of your program.
If for some reason you don't want to rely on using a version of Python that
knows about this future behavior, you might consider
dx = float(abs(i2 - i1))/min(i2, i1)
as an alternative.

I prefer to multiply by 1.0 That has the advantage it continues to work
if your numbers happen to be complex.
