how do a round a figure to the nearest 2 decimal places?

[tippytarka]

i'm trying to round a figure to two decimal places. the result i get is '2234.6789' and i want the result to look like this...... '2234.68'

here's my code that calculates my total cost and prints to the browser


// CALCULATE total cost
function total_cost($total_base,$total_addtional_selects,$total_vat) {
 $price = $total_base + $total_addtional_selects + $total_vat;
 return $price;
}

$total_base = purchase_selected_job_titles($licence,$count);
$total_addtional_selects = $tel_value + $email_value;
$total_vat = vat($vat_base,$vat_tel_email);
$final_total_cost = total_cost($total_base,$total_addtional_selects,$total_vat);
print "$final_total_cost";


cheers!

$final_total_cost = round(total_cost($total_base,$total_addtional_selects,$total_vat), 2);

Not spelled out - but if you read the PHP manual entry for number_format it appears that it rounds the number automatically to the desired number of decimal places:

<?php
$number = 1234.5678;
// english notation without thousands seperator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57
?>
