title: Using numbers with multiple decimal points (ex. 1.4.4) in MySql, is it possible?
body: <p>I'm creating a system for keeping track of which type of software, and which version of the software is licensed for each company. Some of the software has version numbers like 1.1.4 or similar with more than one decimal point. </p>
  
  <p>I have tried saving it as a varchar for now, since I couldn't find a numerical data type that would take more than one decimal point. And, storing it as a varchar is fine, but I need to be able to search it for >= 1.1.2 or &lt;= 2.5.1 and when I do that the system crashes. Searching for >= 1.2  will yield the result 2.5.1 for instance, but I would like to be able to search that last number too for accuracy. </p>
  
  <p>Is there some datatype I'm missing (I'm quite new to this) or is there some other easy way of solving it?</p>
