How can I round a double to 2 decimal points? (Swift)

Question

Here's the code:
func quarters(changeDue:Double) -> Double
{
var quarters = (changeDue/0.25).rounded(.down);
let changeDue = changeDue - (quarters * 0.25);

if quarters == 1.0
{
print(String(Int(quarters)) + " quarter");
}
else
{
print(String(Int(quarters)) + " quarters");
}

return changeDue
}

let changedue = 0.52;
let changeDue = quarters(changeDue:changedue);
print(String(changeDue) + " remain");

I'm trying to round (up) so that the output for "changeDue" is a two-decimal point double
