yeah, my patch only works for rational numbers. <br><br>will have a look at the article / method you posted, claude.<br><br><br><br><br><br><br><br><div class="gmail_quote">On Fri, Dec 16, 2011 at 7:49 PM, Claude Heiland-Allen <span dir="ltr"><<a href="mailto:claude@goto10.org">claude@goto10.org</a>></span> wrote:<br>

by the way, here is the method i used:<br>
<br>
first, convert the decimal part to a fraction in the form of n/100000<br>
next, find the highest common factor of n and 100000<br>
(using the 'division method' like this:<br>
<a href="http://easycalculation.com/what-is-hcf.php" target="_blank">http://easycalculation.com/<u></u>what-is-hcf.php</a> )<br>
<br>
then just divide n and 100000 by that factor.<br>

I don't think that method will give happy results for most simple fractions. Plus it's useful to get approximations that are simpler or more accurate, like 3 or 22/7 or 355/113 for pi..<br>
<br>
Your patch doesn't work very well for me:<br>
<br>
input: 1/7<br>
fraction: 2857/20000<br>
input: 8/9<br>
fraction: 11111/12500<br>
input: 7/11<br>
fraction: 15909/25000<br>
input: 11/17<br>
fraction: 4313.67/6666.67<br>
<br>
(input is "$1 $2"--[/], so as accurate as floating point is...)<div class="im"><br>
<br>

actually, that means it's accurate to 6 decimal places, i guess.<br>

There's a way to get a "simple" fraction like 1/7 instead of 143/1000 or whatever, could be possible to implement in Pd? (I've not tried.)<br>
