Round UP to the closet 2 decimal places ??

Copy linkTweet thisAlerts:

Hi,

I am using this to work out the VAT on an item (17.5%)

[code=php]
$VAT_Price = (((17.5/100) * $UnitPrice) + $UnitPrice)
[/code]

The problem is if the unit price is 3.45 the $VAT_Price is coming out at 4.05375 but it can only be two decimal places ??

Thanks
Ada,

$VAT_Price = sprintf("%.2f", (17.5/100 * $UnitPrice) + $UnitPrice + 0.005);
[/code]

Yep. ?

sprintf("%.2f", $value) will round $value to the nearest hundredth, so adding .005 makes sure that it always rounds up. (Possibly adding .00499999 would be better?)

@ShrineDesignsApr 19.2005 — or you could do this[code=php]<?php
$vat_price = ((17.5 / 100) * $unitprice) + $unitprice;
echo round($vat_price, 3);
?>[/code]

Success!
