Here is a short test program :
<?
#test.php of integer operation by /
  $total=13;
  printf ("total %d  type %s<BR>",$total,gettype($total));
  $each=10;
  printf ("each %d  type %s<BR>",$each,gettype($each));
  $page=$total/$each;
  print ("Page is $page");
?>

The output is 1.3
not as the expect 1

"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) and the quotient is an integer. ****If either operand is a floating-point value, or the operation results in a non-integer value, a floating-point value is returned.****"

Did you see my program?,and dir you run them?
obviously, the two operands are ***integers ***.

Again:

****If either operand is a
floating-point value, or the operation results in a non-integer value, a
floating-point value is returned.****

The division returns a floatingpoint value.

Yes, did you read the part in ****?  Obviously not.

****If either operand is a floating-point value, or the operation results in a non-integer value, a floating-point value is returned.****

The operation 13/10 will result in 1.3 which is a float, so a floating point value is returned.
