PHP Rounding Up Issue

Hi Chaps,

I have an SQL query that calculates a word count multiplied by a fixed figure:

"...$pricegross = ($row_rsInvPending['projanalysis_total']*$row_rsInvPending['costbase']);..."

Then use a bit of php code to round up the figure to 2 decimal places....

<?php echo number_format($pricegross, 2, '.', ''); ?>

I then total up $pricegross for all records:

".....SELECT SUM(projanalysis_total) as total_pricegross..."

If I have two records:

($pricegross) 1. £2.295

($pricegross) 2. £2.295

There are both displayed as £2.30, which is what I want

Then the total ($total_pricegross) shows up as £4.59, but what I want is: £4.60

Is this possible?

Hope this is clear?!
