title: How can a string.match include decimal points?
body: <p>So I am trying to get string.match to not only get '%d+'(any string of strait digits) but I want it to include decimal points IF they are present. I can't make the pattern '.%d+' or '%d+.%d+' because then those would detect any punctuation and wouldn't get a plain non decimal number</p>
  
  <p>I'm so lost here</p>
