If you want to divide value need result as int then normally we use intval function but some case it give wrong result. This is simple code which result wrong

<?php
echo  intval(69.6  / .1);
?>

Then final result is :

 Result :695 // which is wrong 
 Result will be : 696

so in this case first we need to make round value result then convert int, this is demo code which will work

<?php
echo  intval(round(69.6  / .1),2);
?>

then the result is :

Result is : 696 // which is correct

So if you divide something then need result as int then use round function
