title: Regex that does not allow zeros
body: <p>I use this regex:</p>
  
  <pre><code>/^(?!0000)(?!0+(?:[.,]\d{1,2})?$)\d{1,4}(?:[.,]\d{1,2})?$/
  </code></pre>
  
  <p>It allows decimal numbers (. and , separators), with two digits after the separator. It does not allow zero values. What I want to do is to make it allow numbers like 0.1 and 0.09 etc... Here it's impossible to write any number starting with 0. I don't know how to do this. Any idea?</p>
  
  <p>Thanks.</p>
