2.0 is not an integer. is_integer(2.0) returns false, which is '' in
string contexts.

It's just that is_integer( $a_double_value ) doesn't seem to return
true nor anything else if the double matches a integer value. Just try
this script:
<?php
$a = 2.0;
$b = 1.0;
echo is_integer( $a/$b );
echo is_integer( 2.0 ); // Doesn't output anything
echo is_integer( 2 );
echo is_integer( 2/1 );
echo is_int( 2 ); // These 3 test do output "1"
?>
