NEWB: dividing numbers

[Lo]

I just tried python first time.

2/3

the result is zero

I want the result to be .333...

How do I get this?

Thanks a lot

Float type must be specified explicitly:
2/3.0 or 2.0/3

In Python 3.x operators behave differently and '2/3' would give float
number as a result.

I want the result to be .333...

Than try: 1/3.0 because 2/3.0 will never show you that

Well, that's not going to happen - 2/3 is .666 if not done with integers...

How do I get this?

Use floating points.

0.6666666666663

Add the following to the top of your program:

from __future__ import division

That tells Python to use the proper kind of division, which is now the
default in Python 3.0.

That's integer division (integer divided by integer is integer).

If you want the result to be floating point then make one of them
floating point:

2.0 / 3

or do this first:

from __future__ import division

In the future and in Python 3.x "/" will always return floating point.
For an integer result use "//" instead.

BTW, 2.0/3.0 still isn't 0.333... ;-)

Hi,

2/3

That's because your dividing an int by an int to an int. The definition
of an int is a "whole number". So just use floating point I think it's
called, this should work, and does just tested with the python
interactive shell:
2.0/3

Cheers,
Daniel.
