title: How to drop printing "0.000*" values in my code but pass everything else through?
body: <p>I am having some trouble coming up with meaningful all-cases covered boolean expression for this:</p>
  
  <pre><code>$vars = [
      "0.000",//do not print this value, as it is "not set"
      "0.00", //do not print
      0.00,   //do not print
      "TBD",  //print
      "14.5", //print
      14.5    //print
  ];
  
  foreach ($vars as $var) {
      if (/* ... */)
          print "$var&lt;br&gt;\n";    //print only the "to be printed" values
  }
  </code></pre>
  
  <p>For one, <code>$var != 0</code> fails.  <code>$var !== 0</code>, also fails.</p>
