In the following script the operator "/" does NOT perform an integer division as said in the documentation:

In chapter "Arithmetic Operators" the online documentation sais: "The division operator ("/") returns an integer value (the result of an integer division) if the two operands are integers (or strings that get converted to integers)."

Though the script

<?php echo "1 / 3 = ". 1/3 ?>

produces the following output:

1 / 3 = 0.33333333333333
