title: Grab decimals with regex
body: <p>Good morning,</p>
  
  <p>I'm new at working with regex and need something what I can not find.</p>
  
  <p>I've an expression: 
  ]C193123456789.123
  To get the first digits before the dot I know 
  <code>^93[data.*]\.</code> = 123456789
  ]C1 is my leading Identifier so it doesn't matter.</p>
  
  <p>My question now is, how can I get the digits after the dot? = 123</p>
  
  <p>Thanks</p>
