title: Default size of datatype float in mysql - phpmyadmin
body: <p>I have many float columns, But in phpmyadmin I didn't provide the size  of float  but unlike varchar, it still saves the column

  <ol>
  <li><p>what is the default size of float? </p></li>
  <li><p>should I enter the size manually like Float(10,2)  Or it does not make much performance difference ?</p></li>
  </ol>
  
  <p>Thanks :)</p>
