Round calculation to the nearest pound

Hi guys,

I have the following calc, how can I round it to the nearest pound? £2.50 would be £3.00 and £2.49 would be £2.00 etc...

<?php $TheVar = $rows_product[$i]['product_rrp'] - $rows_product[$i]['product_price']; ?>

Thanks,
Dean

If your variables contain the pound sign, then you'll need to strip that out. Also, if you need the output to include the decimals, you've got number_format().

$rrp = str_replace('£', '', $rows_product[$i]['product_rrp']);
$price = str_replace('£', '', $rows_product[$i]['product_rrp']);

$TheVar = round($rrp - $price);

echo number_format($TheVar,2);

hi.. please use this

float round ( float $val [, int $precision = 0 [, int $mode = PHP_ROUND_HALF_UP ]] )

or

<?php
echo(round(0.60) . "<br>");
echo(round(0.50) . "<br>");
echo(round(0.49) . "<br>");
echo(round(-4.40) . "<br>");
echo(round(-4.60));
?>
