round currency and add comma

[Anon]

I need to round currency and add a comma in the thousands place. Currently I am using an excample from php documentation and it works good but it does not place a numbers after the decimal when that value is 0.

$cash = round($points_forwarded / 400100)/100;
$cert = round($points_forwarded / 250100)/100;

If this value = 2000.20 The value returns 2000.2 I am looking for 2,000.20
Can anybody help me with this?

Thank You

Use number_format. See:

http://www.php.net/manual/en/function.number-format.php

Of coarse I had already been to
http://www.php.net/manual/en/function.number-format.php

not much help, very poorly written.

Any way, here is what I came up with and it works:

$cashr = round($points_forwarded / 400100)/100;
$ffmr = round($points_forwarded / 10);
$certr = round($points_forwarded / 250100)/100;
$cash = number_format($cashr, 2);
$ffm = number_format($ffmr);
$cert = number_format($certr, 2);

Thank You any way

I fail to see what's 'poorly written' in the number_format() page in the manual.
Four parameters that are pretty much self-explanatory.

$points_forwarded=45762434;
$certr = $points_forwarded/250;
$cert = number_format($certr, 2, '.', ',');

echo $certr.'<BR>'.$cert;

number_format() even rounds properly on my system; I wonder if that's just a lucky accident?
