PHP Help. Got a load of variables with numbers such as 9.95, and want to * it by lets say 8, but only want the output to be to 2 decimal place (min and max so that if the numbers 45.4, it would be 45.40) for use with numbers with prices .etc. Anyone gets what I mean please help :), tried using the round() command but it doesnt add like the extra digit onto the end if theres only 1 deicmal place available.

This will do what you want:


$price = round($price, 2);

Nope that what im currently trying to do, ill give you some example code...


$price_monthly = 4.95;
$price_biannually = round($price_monthly * 6, 2);
echo $price_biannually;


This works great BUT, this returns 29.7, but I want 29.70 instead, so its great for some but others it will miss the second decimal, as theres no need, but when using prices/currency .etc you need 2 decimal places, no more and no less :(.

Any Ideas?

Thanks.

Well I suppose I get proven wrong...

;)

4.2.3

Yes that is what I am using and it seems that no longer works as my script is not working now either. Hrmm off to find another way to do it. Will let you know what I find...

I found where someong wrote this and posted it on php.net. There has to be a built in function though so we don't have to use this...

Wow that long =/, wanna cut it up for me so only need the 00 and 0 bit ;), guess i could live with working it out though

LOL
I found a simpler answer....

$formatted = sprintf("%01.2f", $money);


That works... I promise.... LOL

woohoo thanks alot :), if this were real life and you were female id kiss your sweet ass.

ROFL

No problem...

be aware that sprintf can have different results with regard to rounding on different OS's

just had this problem with runing a script I developed on my local box rounding nicely, but on the solaris production box it didn't!
