title: How can I use a regex to determine if a unumber is divisible by 5?
body: <p>I am trying regex to find out whether a number is divisible by 10 or by 5. So basically, I am trying to see whether the number end in 0 or 5.</p>
  
  <p>This is my regular expression
  <code>^[1-9]*0?.0$</code></p>
  
  <p>I encounter issues when the input is 100.0 or 55.0</p>
  
  <p>What should the regular expression be?</p>
  
  <p>Thanks,
  Sandy</p>
