    copied!<p>Alright, so I have a working program that makes golden ratio rectangles based on a length or width given.</p> <p><img src="https://i.stack.imgur.com/Eh4WA.png" alt="Program Shown."> This probably isn't a good practice, but I wrote a <em>String.Slice(start, end)</em> in the extensions class.</p> <p><strong>Here's what I need help with.</strong></p> <pre><code> case 1: //Length l1.Text = value.ToString().Slice(0, 4); l2.Text = value.ToString().Slice(0, 4); h1.Text = (value/phi).ToString().Slice(0, 4); h2.Text = (value/phi).ToString().Slice(0, 4); break; case 2: //Width l1.Text = (value * phi).ToString().Slice(0, 4); l2.Text = (value * phi).ToString().Slice(0, 4); h1.Text = value.ToString().Slice(0, 4); h2.Text = value.ToString().Slice(0, 4); break; </code></pre> <p>Depending on the radiobutton, it finds the length or with based on what you provide. The problem is that with the strings all sliced to 1-4 characters, a number can be shown as </p> <pre><code> "161." </code></pre> <p>(with the period) in the textbox. Is there a way to make it so that only if it ends with a period that the period is removed? Thanks.</p> <p>P.S. Here's the slice function for reference: </p> <pre><code>public static class Extensions { public static string Slice(this string source, int start, int end) { if (end &lt; 0) // Keep this for negative end support { end = source.Length + end; } int len = end - start; // Calculate length try { return source.Substring(start, len); // Return Substring of length } catch (Exception) { try { return source.Substring(start, len - 1); // Return Substring of length } catch (Exception) { try { return source.Substring(start, len - 2); // Return Substring of length } catch (Exception) { return source.Substring(start, len - 3); // Return Substring of length } } } } } </code></pre>
