Re: variables `inheriting' values, rounding

I'd like to encourage you to not top-post and avoid HTML emails if
possible. It's an old email convention many of us still like.

My earlier suggestion to make settings a function that returns the
actual values you want might work here, assuming that the overhead of
a function call isn't a problem in your algorithm.

Barring that, Octave can do functional programming rather well, so I
would structure your code so that your algorithm is contained in a
function and settings is a parameter to that function.

If you go to http://octave.sourceforge.net, click on function
reference at the top and then look at the alphabetical list, you will
find that round is a built-in function that rounds to the nearest
integer. You can easily use this to round to whatever decimal place
you want.
