    <p>I'm new to using c++ so this may be a vector issue. I'm getting a floating point error. I don't think this is a divide by zero error. Any help would be appreciated.</p> <p>The code compiles, but when run the error pops up. "Floating point exception (core dumped)"</p> <pre><code> vector&lt;int&gt; radixSort (vector&lt;int&gt; &amp;numbs, int maxA) { vector&lt;vector&lt;int&gt; &gt;temp1; vector&lt;vector&lt;int&gt; &gt;temp2; for (int i = 0; i &lt; 10 ; i++) { temp1.push_back(vector&lt;int&gt;()); temp2.push_back(vector&lt;int&gt;()); } int x = 1; int plc = 0; while (maxA/x &gt; 0) { plc = plc + 1; x = x * 10; } for (int i = 0; i &lt; (int)numbs.size(); i++) { int aryLoc = numbs[i] % 10; temp1[aryLoc].push_back(numbs[i]); } plc = plc - 1; int modDiv = 100; int intDiv = 10; bool isTemp1 = true; while (plc &gt; 0) { for (int i = 0; i &lt; 10 ; i++) { if (temp1[i].size() &gt; 0) { for (int j = 0; j &lt; temp1[i].size() ; j++) { int aryLoc = temp1[i][j] % modDiv; aryLoc = temp1[i][j] / intDiv; temp2[aryLoc].push_back(numbs[i]); modDiv = modDiv * 10; intDiv = intDiv * 10; } } } plc = plc - 1; isTemp1 = false; for (int i = 0; i &lt; 10 ; i++) { temp1[i].clear(); } if (plc &gt; 0) { for (int i = 0; i &lt; 10 ; i++) { if (temp2[i].size() &gt; 0) { for (int j = 0; j &lt; temp2[i].size() ; j++) { int aryLoc = temp2[i][j] % modDiv; aryLoc = temp2[i][j] / intDiv; temp1[aryLoc].push_back(numbs[i]); modDiv = modDiv * 10; intDiv = intDiv * 10; } } } plc = plc - 1; isTemp1 = true; for (int i = 0; i &lt; 10 ; i++) { temp2[i].clear(); } } } if (isTemp1 == true) { int y = 0; for (int i = 0; i &lt; 10 ; i++) { if (temp1[i].size() &gt; 0) { for (int j = 0; j &lt; temp1[i].size() ; j++) { numbs[y] = temp1[i][j]; y++; } } } } else { int y = 0; for (int i = 0; i &lt; 10 ; i++) { if (temp2[i].size() &gt; 0) { for (int j = 0; j &lt; temp2[i].size() ; j++) { numbs[y] = temp2[i][j]; y++; } } } } return numbs; } </code></pre> <p>thanks for the help seems to be working now when I found my errors here is the fixed copy</p> <pre><code>vector&lt;int&gt; radixSort (vector&lt;int&gt; &amp;numbs, int maxA) { vector&lt;vector&lt;int&gt; &gt;temp1; vector&lt;vector&lt;int&gt; &gt;temp2; for (int i = 0; i &lt; 10 ; i++) { temp1.push_back(vector&lt;int&gt;()); temp2.push_back(vector&lt;int&gt;()); } int x = 1; int plc = 0; while (maxA/x &gt; 0) { plc = plc + 1; x = x * 10; } for (int i = 0; i &lt; (int)numbs.size(); i++) { int aryLoc = numbs[i] % 10; temp1[aryLoc].push_back(numbs[i]); } plc = plc - 1; int modDiv = 100; int intDiv = 10; bool isTemp1 = true; while (plc &gt; 0) { for (int i = 0; i &lt; 10 ; i++) { if (temp1[i].size() &gt; 0) { for (int j = 0; j &lt; temp1[i].size() ; j++) { int aryLoc = temp1[i][j] % modDiv; aryLoc = aryLoc / intDiv; temp2[aryLoc].push_back(temp1[i][j]); } } } modDiv = modDiv * 10; intDiv = intDiv * 10; plc = plc - 1; isTemp1 = false; for (int i = 0; i &lt; 10 ; i++) { temp1[i].clear(); } if (plc &gt; 0) { for (int i = 0; i &lt; 10 ; i++) { if (temp2[i].size() &gt; 0) { for (int j = 0; j &lt; temp2[i].size() ; j++) { int aryLoc = temp2[i][j] % modDiv; aryLoc = aryLoc / intDiv; temp1[aryLoc].push_back(temp2[i][j]); } } } modDiv = modDiv * 10; intDiv = intDiv * 10; plc = plc - 1; isTemp1 = true; for (int i = 0; i &lt; 10 ; i++) { temp2[i].clear(); } } } if (isTemp1 == true) { int y = 0; for (int i = 0; i &lt; 10 ; i++) { if (temp1[i].size() &gt; 0) { for (int j = 0; j &lt; temp1[i].size() ; j++) { numbs[y] = temp1[i][j]; y++; } } } } else { int y = 0; for (int i = 0; i &lt; 10 ; i++) { if (temp2[i].size() &gt; 0) { for (int j = 0; j &lt; temp2[i].size() ; j++) { numbs[y] = temp2[i][j]; y++; } } } } return numbs; } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
