Strings seems to get converted to double for "==" comparison.

<?
$a = (string) 2.2;
$b = (string) 2.20;
if ( "$a" == "$b" ) {
        echo "The string $a equals string $b";
} else {
        echo "The string $a does not equal string $b";
}
?>

Clearly the "strings" 2.2 and 2.20 should not be equivalent.

If this isn't considered a bug then how does one compare two strings like this. I've tried :
if (strval($a) == strval($b) 

but the only successful workaround I've found is:
if ( "$a" == "$b" && strlen($a) == strlen($b) ) {
