PHP Help. Returning a value to 2 decimal places.

Ok.

Im coding a script and after you order it adds on 17.5% VAT. But this causes problems and gives out a number. Something like $29.36325 when it should be $29.36

$vat = 24.99 / 100 * 17.5;

$gt = $vat + 24.99;

echo ("You ordered $_POST[iname]. The price is $24.99 (excluding VAT).  The grand total is $$gt "); 

Thats the code im using. If anybody could help me it'd be great. I tried a few codes but nothing so far has worked.

Display it as a image for some reason then add into it imagechar so it limits the text to about 20 so it misses out the other bits.

round();

it should end up like:

$vat = 24.99 / 100 * 17.5;

$gt = $vat + 24.99;

echo ("You ordered $_POST[iname]. The price is $24.99 (excluding VAT).  The grand total is $");
echo round ($gt, 2);

Thanks all. I tried the round function but it didn't work. If anyone needs this use the money_format() function.
