check if $val is a whole?

So i wasn't quite sure how to word the title lol what i got is a kill death ratio type deal going on and i need a way to check if the number is a whole or not..or possibly count the number of decimals? So for example if they have a kdr of 2/1 it will show 2.00

PHP:

$kdr = round($kc/$dc, 2);

is $kc and $dc the kills and deaths?

yes kill count and death count

I was actually trying to add useless decimals just for the look kinda and thats how most games work like cod, like if they have 20 kills and 1 deaths instead of $kdr = round($kc/$dc, 2); showing 20 it will show 20.00 idk how that would work with round tho..

But if +0 will take away the useless decimals..will -0 add one? 0.O doesn't seem to be right lol

never mind i found a way

PHP:

$decimals = ( (int) $kdr != $kdr ) ? (strlen($kdr) - strpos($kdr, '.')) - 1 : 0;

I was thinking about this:

PHP:

$kdr = round($kc / $dc * 100) / 100;


After converting it into a string, these are the results on my local tests:

Code:

[email protected]~~ MINGW64 /
$ php -r '$kc = 20;
$dc = 10;
var_dump("" . (round($kc / $dc * 100) / 100));'
string(1) "2"

[email protected]~~ MINGW64 /
$ php -r '$kc = 25;
$dc = 10;
var_dump("" . (round($kc / $dc * 100) / 100));'
string(3) "2.5"

[email protected]~~ MINGW64 /
$ php -r '$kc = 26;
$dc = 17;
var_dump("" . (round($kc / $dc * 100) / 100));'
string(4) "1.53"

I used `"" . ` instead of `(string)` since I think that will be the way how you use the number (concatenate it with a string). I suppose there is no techincal difference though.

The round(num * 100) / 100 method was supposed to be something used in languages like JavaScript where Math.round() doesn't have a decimal place precision parameter, but I find that it is useful here too

I would do this:

PHP:

$kdr = sprintf("%.2f", $kc/$dc);


Thanks for the idea btw your killRate plugin is cool but i just wanted something simple and seems how i already have something that deals with deaths and kills i figured id just add a kill and death tracker to that. I hope to have it work with factionspro as well to get the kdr of a whole faction. Also your coding style is wild..in a good way lol i love the way you did killRate XD i didnt bite your code btw lol idk how to use databases yet

Instead of making a new thread..can anyone tell me how i might go about getting the top kdr? should i put topkills and topdeaths in a function then make sure the array key is the same and if not..uhh. idk how to go about that.

PHP:

       
              case "topkills";
                   if($this->kills != NULL){
                    $kills = array_values($this->kills->getAll());
                    $topkills = max($kills);
                     $name = array_search($topkills, $this->kills->getAll());
                       $sender->sendMessage(TextFormat::BOLD.TextFormat::AQUA.(strtoupper($name))." §2has the top kills of ".TextFormat::RED.$topkills);
                   }else{
                    $sender->sendMessage(TextFormat::BOLD.TextFormat::RED."No kills found on this server");
                   }
                   break;
             
              case "topdeaths";
                   if($this->deaths != NULL){
                    $deaths = array_values($this->deaths->getAll());
                    $topdeaths = max($deaths);
                     $name = array_search($topdeaths, $this->deaths->getAll());
                       $sender->sendMessage(TextFormat::BOLD.TextFormat::AQUA.(strtoupper($name))." §2has died the most at ".TextFormat::RED.$topkills.TextFormat::BOLD." §2deaths");
                   }else{
                    $sender->sendMessage(TextFormat::BOLD.TextFormat::RED."No deaths found on this server");
                   }
                   break;
                   

so i must find the array key that has the most kills..and least deaths but that also needs to be the highest kdr /: am i over complicating this?..lol

so

PHP:

var_dump("" . (round($kc / $dc * 100) / 100));'

will add the usless .00?

Don't hardcode the color codes...

What's that mean? don't use § after already using a TextFormat?

Or just don't use them a lot?..causes lag?

Don't use the § character. That may get changed in the future.

Ah crap. I use that a lot lol TextFormat going to be around still?

I agree wth aliuly. This is what I would've used.

PHP:
$kdr = sprintf("%.2f", $kc/$dc);

will try it, i got it but the way i found above is kinda a weird way to go about it i guess..it just counts the decimal placed then i must check if its null or 1 so on and so forth whats the deal with "%.2f" ? ive never seen that.

PHP:

sprintf("%.2f")

It basically means that the situation will be treated as a float. As it has a "2", the number will have 2 decimal points. Example: 10.78
