round number to the nearest...

I am looking for a way to round a number (which will be displayed as a
dollar amount) to the nearest nickel. Using the php round function
only allows you to control the number of decimal places in a number. I
need to round to the nearest .05. For example: 5.36 would be rounded
to 5.35, 10.49 would be rounded to 10.50, etc.. Any help would be
greatly appreciated.

Here goes the worst ever php code posted to this newsgroup .

But hang loose as somebody will be along shortly with a one line
solution :-)



$demo=12.34;

print "demo = $demo

";

$daffyduck=strlen($demo);
print "daffyduck = $daffyduck

";

$mickymouse=substr($demo,$daffyduck-3,1);
print "mickymouse = $mickymouse

";

if ($mickymouse==".")
{

$snowwhite=substr($demo,0,$daffyduck-1);
print "snowwhite = $snowwhite

";

$dwarfs=substr($demo,$daffyduck-1,1);
print "dwarfs = $dwarfs

";

if ($dwarfs==0) {$poop=0;}
if ($dwarfs==1) {$poop=0;}
if ($dwarfs==2) {$poop=0;}
if ($dwarfs==3) {$poop=5;}
if ($dwarfs==4) {$poop=5;}
if ($dwarfs==5) {$poop=5;}
if ($dwarfs==6) {$poop=5;}
if ($dwarfs==7) {$poop=0;}
if ($dwarfs==8) {$poop=0;}
if ($dwarfs==9) {$poop=0;}

$albundy=$snowwhite . $poop;
print "albundy = $albundy

";

}

?>

Multiply by 20, then round, then divide by 20. That should do it.

function round_to_nickel($number)
{
return ( round( $number*20 ) /20);
}

I do admit - your solution is "ducky"! - and it "dwarfs" the ideas I
came up with.

Of course, this is a pure snow white PHP solution!

Krustov,

I am loving the script but I think I will have to work on the $poop a
bit. lol, When I get to a situation where the 1st digit after the
decimal needs to be rounded up, it still rounds down. This adds even
more diffuculty to it when I have a number like 5.98 as the entire
number will round to 6.00. Thanks for the help!

which assumes that a dot will always denote cents, which doesn't make sense.

Dont you mean it will round down to 5.90 ? .


if ($dwarfs==7) {$poop="plop";}
if ($dwarfs==8) {$poop="plop";}
if ($dwarfs==9) {$poop="plop";}

if ($poop=="0")
{
$albundy=$snowwhite . $poop;
print "albundy = $albundy

";
}

if ($poop=="5")
{
$albundy=$snowwhite . $poop;
print "albundy = $albundy

";
}

if ($poop=="plop")
{
$albundy=$snowwhite . "0";
$albundy=$albundy+0.10;
print "albundy = $albundy

";
}

Havent tested the +0.10 and it probably wont work .
