converting to 2 decimal places in php

[backpacklondon.com]

Hello again,

Another quickie....

How do I convert a number with many decimal places, to just 2 decimal places please (i.e. like with prices)?

e.g. $total = 1.222222;

so how would I make $total = 1.22

Thanks,

Jason

Hi Jason,

I had (almost) the same problem. This thread may be able to help you out:

hmmmmm not quite,

Thanks insomniac, but I think this will remove all decimal places!!!

I'd like to keep 2 of them, e.g. £14.33


So any other ideas please?


Regards,

Jason

Jason,

I know that if you play around with that code in the other thread, you can get the result your looking for.

$var = sprintf( "%.2f", $var );

Should return $var to 2 decimal places.

perhaps


$value = 14.8366723786;
// change to whatever value...

$value = $value * pow(10, 3);

$value = floor($value);

$value = (float) $value/10;
(float) $modSquad = ($value - floor($value));
$value = floor($value);
if ($modSquad > .5){
$value++;
}

$value = $value / (pow(10, 2));

okay.. I was beaten to it.. and my way is sooooooo complicated but never mind

There is a function in php for this

$var = number_format($var, 2);

where number_format converts the given string to the number of decimal point specified, in this case 2
