You can't turn a decimal representation into a decimal with a function that only returns integers. You might want `floatval` instead. — Cᴏʀʏ, Jan 03 '17 at 18:32
`(double)"0.05";` - as Cory said an int can't have decimals... — Gerrit0, Jan 03 '17 at 18:34

Type cast it as a float

$x = "0.05";
$y = (float)$x;
var_dump($y); // float(0.05)

Note that this may require some finessing as floats are notoriously imprecise

You are using int-val. This will give you an integer answer. Since you are working with a decimal fraction, what you need is floatval.

floatval("0.05");
