title: Weird Numbers/Characters within code
body: <p>I've downloaded an open-source program, and found this:</p>
  
  <pre><code>public static final char playerNameXlateTable[] = { '_', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '[', ']', '/', '-', ' ' };
  
      public static String longToPlayerName2(long l) {
          int i = 0;
          char ac[] = new char[99];
          while (l != 0L) {
              long l1 = l;
              l /= 37L;
              ac[11 - i++] = playerNameXlateTable[(int) (l1 - l * 37L)];
          }
          return new String(ac, 12 - i, i);
      }
  </code></pre>
  
  <p>And I tried figuring out what the <code>37L</code> was for.
  I first thought it might be Hex, but I found that Hex doesn't have any 'L's.</p>
  
  <p>Does someone have a clue what type of that is? And what it converts to in actual number?</p>
  
  <p>Thank you very much!</p>
