how to get a following zero as a numerical?

[Cloudrunner]

So I want to display the following zeros in a 2 precision php rounded number, but I need it as a numerical...how do I do that?

i.e.

$amount = 1;
$exchange = 1.5;
$total = round($amount*$exchange);

echo $total;how do I get that to display as 1.50 as a numerical (as opposed to the string that the number_format(); function gives)?

Don't round it if you want the decimal.


$amount = 1;
$exchange = 1.5;
$total = ($amount*$exchange);

echo $total;


that will echo 1.5. If you want a trailing zero:



$amount = 1;
$exchange = 1.5;
$total = ($amount*$exchange);

if ((strlen($total) ==1) && $total != 0) { $total = $total.".00"; }
/* adds decimal and two following zeros if total does not = ? if you want 0.00 remove the "&& $total !-0" portion of the if statement. */

if (strlen($total) ==3) { $total = $total."0"; }
/* adds traling zero for x.x amount. */

echo $total;


You don' need a statement for strlen = 2 because that would be X. and there will never be a decimal with only 1 digit and if it's a two digit whole number you do not want to add a zero. I don't know how long your rounding will be. if it's 4 digits behind the decimal you may need a couple more statements to compensate.

This only effects display of $total it doesn't alter the database.

This is how I do it on my site.

A vastly easier and cleaner solution is to use the number formatting functions PHP gives you, including the formatted string functions like sprintf().

wow that is easier filburt. Thanks.

<i>edit: </i>NVM, got this one figgered out as well...was not a numerical vs. string issue...was a formatting error within the currency notation...

Thanks!
