variable types

Hi. I use php4 on Windows 2000. I have the following problem, which I hope someone can help me about.

I use the following:

<?
$a = 1.2;
echo $a;
?>

it states 1 ???

whats the problem. Why doesnt it state 1.2? echo gettype($a); states double, so the type should be right. Using $a = 1.2e3 or $a = (double) 1.2 gives me the same result. whenever I use doubles in expressions like $c = ($a * $b); where $a and $b are doubles it seems to be using integer values, even if I use the cast operator (double).
