title: Regular Expression check only once for a single character and contains more then one number?
body: <p>I would like to build up a regex expression that checks in the text if the string contains a single dot between numbers and that there are more then one number.</p>
  <p>My text example would be:</p>
  <pre><code>11.00 11.000 1.0 1 1 2.
  </code></pre>
  <p>I would like to check that text contains only single dot and I would to check text contains more then one number either 1 or like this 111.00. How can I do this.</p>
  <p>My current expression checks for more then one dot and it not checking if the text contains more then one value of the correct format 1.1 or 1. Also I am checking for new lines and any number of spaces as follows:</p>
  <pre><code>/^[0-9 .\n\t]*$/  
  </code></pre>
