Adding decmals to numbers

[epp_b]

I need to insert a decimal into a the proper character into a string (or integer, if we're being data type specific)

For some reason, this doesn't work (why?)...

$number = "25";

if (!ereg(".", $number)) {
$price_ .= ".00";
}

if (ereg(".", $number)) {
if (!ereg(".00", $number)) {
$number .= "0";
}
}

echo $number;

And, yes, the variable $number has to be a string, for reasons too lengthy to explain (or maybe I'm just too tired right now)
