[SOLVED] help please.

[seany123]

basically i have this code:

 

<?=($player->exp / $player->maxexp * 100);?>%

 

 

but it displays things like 50.5458565999% where i only want it to display 50% or 51%

Well I couldn't write what I am thinking in that same syntax short-cut format, but essentially, you could try using a condition to round the results.

 

example:

$roundup = 235;
$rounddown = 234;

$t = 234.232;

if ($t{5} >= 5)
{
echo $roundup;
} else {
echo $rounddown;
}

 

there's probably an easier way to do it, but you could get creative with that. Given what I see from your code, you're using classes. So perhaps create a method to sort it in that way, and instead of calling the variable directly like you did, call the value of a method.

 

IE:

 

 <?=($player->expRounded() / $player->maxexp * 100;?>

 

 

 

EDIT: here's an example of a method:

 

<?php

function expRounded()

{

$exp = $this->exp;

$nodecimal = strstr($exp, '.', true);

$last = sub_str($nodecimal, -1);

$roundup = substr_replace($nodecimal, $last+1, -1, 0);
$rounddown = substr_replace($nodecimal, $last-1, -1, 0);

if ($last >= 5)
{
echo $roundup;
} else {
echo $rounddown;
}

}

?>

 

 

I didn't test any of this, and don't plan to, but that should give you what you're looking for, for any number.

im confused sorry

 

where all these numbers are coming from etc.

 

isnt there a way to use format_number...or anything like that?

[mrMarcus]

try number_format(), where $num is the number (percentage, etc.), that you would like rounding (formatting) :

$num = 50.5458565999;

echo number_format($num, 0, '.', ''); //returns 51

1 will round to the tenth .. 2 would round to the hundredth, 0 returns no decimal place(s), etc.

 

the above will return 51.

 

perhaps it will help.

[seany123]

for that i will have to make a seperate variable and echo it..

 

would this work?

 

$exppercent = ($player->exp / $player->maxexp * 100);

echo number_format($exppercent, 0, '.', '');

[teynon]

<?=round($player->exp / $player->maxexp * 100);?>

[mrMarcus]

try that :

 

$exppercent = number_format(($player->exp / $player->maxexp * 100), 0, '.', '');

[teynon]

PHP has a cool feature called round. Like i posted above mrMarcus. Use round to round. Use ceil to round up, use floor to round down.

[seany123]

try that :

 

$exppercent = number_format(($player->exp / $player->maxexp * 100), 0, '.', '');

 

thats exactly what i need.

 

thankyou.

[teynon]

Wait, why would you use that instead of round? What am I missing?

nothing, its just i like to have my code a certain way so i understand it better... even though the round function sounds perfectly simple, ive never used it before...

 

on other notes.. my entire site uses this method so making an exception just for this page doesnt sound right to me (id rather have it all consistant).

 

thanks
