title: JavaScript - How to create random longitude and latitudes?
body: <p>I am trying to create random longitude and latitudes.  I need to create numbers between 
  -180.000 and +180.000.  So, I might get 101.325 or -3.546 or -179.561.</p>
  
  <p>Can you tell me a quick formula for that?  </p>
  
  <p>Thanks to everyone for your help. I have combined a couple of examples to suit my needs.  Yes, I could shorten the code, but this really helps to see what's going on.</p>
  
  <pre><code>// LONGITUDE -180 to + 180
  function generateRandomLong() {
      var num = (Math.random()*180).toFixed(3);
      var posorneg = Math.floor(Math.random());
      if (posorneg == 0) {
          num = num * -1;
      }
      return num;
  }
  // LATITUDE -90 to +90
  function generateRandomLat() {
      var num = (Math.random()*90).toFixed(3);
      var posorneg = Math.floor(Math.random());
      if (posorneg == 0) {
          num = num * -1;
      }
      return num;
  }
  </code></pre>
