{math equation="price-(price*.30)" price=$products[product].price format="%d.00" assign=unformatted}

Would this do the trick?

format="%d.00" seems to round to the nearest dollar...

format="%.2f" is better but it truncates the string in stead of rounding it, so for 30% off 2.95 we are displayed $2.06 in the product window, but it is $2.07 when it's added to the cart because the actual price of $2.0666* is round up.

format acts on the numeric as if it is a string.

Where you able to make the adjustments to the smarty modifier plugin for formatprice, if so I'd like to see a snippet if possible. ;)

http://smarty.php.net/manual/en/language.modifier.string.format.php

so would using the global discount thing as mentioned before and then altering the smarty string_format command to round up to the nearest penny or cent be ok ?

It would be best to round to the closest penny, actually, since that's what the calculation for the shopping cart does.

Go to http://www.morecomics.net and add the item that is normally $2.95 to your cart and you'll see what I mean. It is displyed on the page as $2.06, but the price displayed in the cart area is $2.07.

Here is the code that I am currently using:
When I tried using the code that is mention at http://smarty.php.net/manual/en/language.modifier.string.format.php - {$number|string_format:"%.2f"} all I got were values like this:

$2.26
$7.20

That is, everything had "2" in the first place after the decimal point.

I'm getting puzzled here!
