PHP - Rounding Down To Nearest 5 Or 0

hi there all,

I need some help for rounding currency issue..

example:

0.98 round to 0.95
0.95 when round = 0.95
0.91 roun to 0.95.

mean.
i wanna round the end of number 0.98.
if the end of number is 0.01,0.02,0.03&0.04 it would be automatic round to nearest 0.05
*0.01 round = 0.05
*if the mineral water =$0.71 i should get $0.75

and if the end of number is 0.06,0.07,0.08,0.09 it would automatic round to nearest -0.05
*0.06 round = 0.05
*if the mineral water = $0.79 then i should get $0.75

i had googling this for 2months and no answer.. 
please help me.TQ

How can I round this with 2 decimals:

Code: [Select]
echo " $row[team_treasure] ";
I've tried round($row[team_treasure],2) but doesn't seem to work inside my echo tags :/

Hi all,

Can anyone please help me with my problem.

I want to know how to round a decimal - eg. 12.34 to the nearest .10 so it would be 12.30 or if 12.35 go to 12.30 or 12.40.

// my example:

round(12.34, 2);

// I want to to go to: 12.30

Any help is greatly appreciated.

I am trying to take a number (three for example) and want to round it to five, or sixty-seven up to seventy.  I looked at round and ceil, but those don't seem like they are the right things.

Thanks,
Joseph

Bascially i add a couple numbers up and display the sum.

sometimes the number is something like this: 234.237

i want it to display : 234.24

i realize its needs "round()" in it but i dont know how to use it..

any help?

Hi,

Having trouble rounding the output. I would need to be sure the output is not longer than 2 spaces after comma.
Any ideas?

My code
Code: [Select]
<script type="text/javascript">
$(document).ready(function() {
  $("<?php echo "#".$input_end_time; ?>").blur(function(){
   var start_time = $("<?php echo "#".$input_start_time; ?>").val();
   var end_time = $("<?php echo "#".$input_end_time; ?>").val();
  $.getJSON("include/timedifferencecalculation.php?s="+start_time+"&e="+end_time, function(data){
   var success = data.success;
    if (success == 1) {
     $("<?php echo "#".$input_difference; ?>" ).val(data.hours + " h " + data.minutes + " m ");
  if (data.hours + data.minutes/60 >= 6){
$("<?php echo "#".$hours_difference; ?>").val(data.hours + data.minutes/60 - 0.5);
}else { $("<?php echo "#".$hours_difference; ?>").val(data.hours + data.minutes/60); }
  }else { $("#message").text("Viga! " + data.reason); }
    })
    });
  });
</script>

Code: [Select]
This is before
$("<?php echo "#".$hours_difference; ?>").val(data.hours + data.minutes/60 - 0.5);

This is what im trying to get but its not working.
$("<?php echo "#".$hours_difference; ?>").val( round(data.hours + data.minutes/60 - 0.5), 2 );

Hey Everybody,

I was replying to someone elses question about number formatting and came up with a class that will format a number of any length with decimal or not, without rounding. It works perfectly, but after a comment by a noteworthy member my curiosity was aroused.

Is there an easier/faster/better way to achieve this??


My Object:

<?php

/*GHETTO NUMBER FORMATTER v1.0*/

class ghettoNumber {

private $input;
private $output;

public $whole;
public $decimal;
public $number;

function __construct($input){
$this->input = $input;
$this->output = $output;
$this->number = $number;
$this->whole = $whole;
$this->decimal = $decimal;
}

private function ghettoFormat(){

//Split number at the .(decimal)
$this->number = explode('.', $this->input);
//Define the whole number
$this->whole = $this->number[0];
//Format the whole number
$this->whole = number_format($this->whole, 0,'', ',');
//Define the decimal
$this->decimal = $this->number[1];
//Format the decimal
$this->decimal = rtrim($this->decimal, '0');

if(is_string($this->input)){
$this->output = $this->decimal != '' ? $this->whole.'.'.$this->decimal : $this->whole;
}
else{
$this->output = '<strong>ERROR:</strong> Input arg must be passed as type: <em>string</em>';
}

//Return result
return 'Original - '.$this->input.'<br>
  GhettoFormat - '.$this->output.'
<br><br>';

}

public function makeItGhetto(){
return $this->ghettoFormat();
}
}

?>


Sample Instantiation:

$ghettoFormat = new ghettoNumber('12565456565.123401201001210000');
                print $ghettoFormat->makeItGhetto();



I will reiterate my question once more...
Is there, in your opinion, a BETTER way to achieve this (number formatting w/o rounding)?

Thanks People,

E

Here is the number:



$GrandTotal = "68.835";
$Deposit = round($GrandTotal , 2) * .5;

echo $Deposit;



I am looking for: 68.84 but the function doesn't seem to work right.

Any help?

I am very new to PHP and programming in general. About 3 weeks into this.
I have this simple expression and some echo in my code.

    $x1 = $lat_b + $lat_a1;
    echo "<br>lat b: ".$lat_b;
    echo "<br>lat a1: ".$lat_a1;   
    echo "<br>x1: ".$x1;

$lat_b and $lat_a1 are derived from some xml extractions from a yahoo geocode api (that part works fine).

The results of the expression and echos above are as follows:

    lat b: 40.402866
    lat a1: 40.252590
    x1: 80

Why is $x1 rounding automatically on me?

Later, I substituted the expression above with  $x1 = 40.402866 + 40.252590 ; The new result (shown below) makes sense to me.

   lat b: 40.402866
   lat a1: 40.252590
   x1: 80.655456

Hi fellas,

Can anyone show me why my script is still rounding up / down?

printf ("<tr> %s Avg gun Ahit %%</td> %s %.2f %%</td></tr>\n",$tdo,$tdor,number_format($ahit/$fired*100, 3, '.', ''));

Do I have a syntax error as I cannot get my math equation to display more than 2 decimal places even though it's set to 3?

Any help or advice would be really great.

I need to round a number based on it's decimal. 3 or below should round down, 4 should round up to 5, 6 and 7 should round down to 5; 8 and 9 should round up to the next whole number.

The below is returning 3 from 2.16.
Code: [Select]
<?php
$a=2.16;
$i=round($a, 1);
$b=$i;

$i=explode(".", $a);
$decimal=$i[1];

if($decimal < 5){
$j=floor($b);
$i= $decimal > 3 ? $j + .5 : $j;
echo $i;
}
else{
$j=ceil($b);
$i= $decimal < 8 ? $j - .5 : $j;
echo $i;
}
?>

EDIT: The explode should have been on $i not $a.

$f15 = 0.345677 (output from sql data pull)

<?php echo number_format ($f15,3); ?>
 output = 0.345

<?php echo ltrim($f15,"0"); number_format ($f15,3); ?>
output = .345677

How do I combine these so that I am BOTH rounding the result AND trimming a leading zero?  Seems I can get one or the other, but not both.

Suggestions on the syntax?

Hello. This is my first post here. I am not an expert developer but I generally manage to do what is asked of me. However, now and then I'm stumped, like now...

I have an online database system for our company in which staff can enter JOB related data, this includes 2 dimensions which they enter in millimetres (mm).

Here's an example

$dimension1 might be entered as 850
$dimension2 might be entered as 1447
$square_metres is the value I need to calculate.

Firstly, I need to round both dimensions up to the next 100mm so the 850 in this example would become 900 and the 1447 would become 1500.

Once I've done that, I need to calculate the square metres (900mm x 1500mm / 1000 was my first thought) but that raised the second thing; adding a decimal point in the result. 900 x 1500 / 1000 = 1350 but I need the result to be 1.350

I know my way around basic PHP code but I'm no expert by any stretch.

If anyone can help me understand how to get this calculation done I would be hugely appreciative.

Thank you

Martin
