    <p>You need to cast one or the other to a <code>float</code> or <code>double</code>.</p> <pre><code>int x = 1; int y = 3; // Before x / y; // (0!) // After ((double)x) / y; // (0.33333...) x / ((double)y); // (0.33333...) </code></pre> <p>Of course, make sure that you are store the <em>result</em> of the division in a <code>double</code> or <code>float</code>! It doesn't do you any good if you store the result in another <code>int</code>.</p> <hr> <p>Regarding @Chad's comment ("<code>[tailsPerField setIntValue:tailsPer]</code>"):</p> <p>Don't pass a double or float to <a href="http://developer.apple.com/mac/library/documentation/cocoa/reference/ApplicationKit/Classes/NSControl_Class/Reference/Reference.html#//apple_ref/occ/instm/NSControl/setIntValue:" rel="noreferrer"><code>setIntValue</code></a> when you have <a href="http://developer.apple.com/mac/library/documentation/cocoa/reference/ApplicationKit/Classes/NSControl_Class/Reference/Reference.html#//apple_ref/occ/instm/NSControl/setDoubleValue:" rel="noreferrer"><code>setDoubleValue</code></a>, etc. available. That's probably the same issue as I mentioned in the comment, where you aren't using an explicit cast, and you're getting an invalid value because a double is being read as an int.</p> <p>For example, on my system, the file:</p> <pre><code>#include &lt;stdio.h&gt; int main() { double x = 3.14; printf("%d", x); return 0; } </code></pre> <p>outputs:</p> <pre>1374389535</pre> <p>because the double was attempted to be read as an int.</p>

    1. CORight. Convert the integers before you perform the division.

    3. CO@Chad: The code looks right. How have you determined that the result is zero? Are you doing something like `printf("%d", tp)`? That tries to print the content of a double as an int, and you won't get the correct results. Your compiler should have warned you if you did that. For a double the format string is `%lf`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
