title: How to properly define the [float] data type in mysql
body: <p>I defined (through PHPMYADMIN) a field with the <code>float</code> data type.<br>
  When I try to insert a number as 78.556677099932222377 it will translate it to 79.<br>
  How do I make it to save the correct number, at least 7 places after the decimal dot?</p>
