[SOLVED] round to nearest 5 or 10 with 2 decimal places

[Vivid Lust]

how could i round to the nearest 5 or 10 with 2 decimal places? Here are some examples:

 

 

1.23 => 1.25

1.26 => 1.30

1.245 => 1.25

1.236 => 1.25

 

thanks!

$vals = array(1.23,1.26,1.245,1.236);
foreach($vals as &$v) {
$v = ceil($v*20)/20;
}
echo '<pre>'.print_r($vals, true).'</pre>';

If to nearest, then round should be used instead of ceil

[JAY6390]

I thought that myself, however round does not work if you do the above with it instead of ceil

[Mchl]

It doesn't?

[JAY6390]

Nope, this would be the output

Array

(

    [0] => 1.25

    [1] => 1.25

    [2] => 1.25

    [3] => 1.25

)

To OP: Do you really want to round to the nearest 5/100ths? If so, your numbers are incorrect, 1.26 is closer to 1.25 than 1.30.

 

Perhaps you want to round up to the next 5/100ths? If that is the case, look to JAY6390's post.

Thanks, how could i "wrap" some code around a single number to achieve this rather than having them in an array? Thanks.

My mistake! I meant to write 1.25 and not 1.30 , sorry guys

[JAY6390]

what do you mean by "wrap" code around it? example?

Just don't do it in an array, but do the change directly.

more or less a function.

[JAY6390]

function round_it($value) {

    return round($value*20) / 20;

}

 

Not sure why you couldn't make one yourself, it's hardly difficult

[Vivid Lust]

function round_it($value) {

    return round($value*20) / 20;

}

Because some of us are noobs. Will try it now, thanks.
