Playing with decimals

[iceraider]

This what with decimals and rounding.

1. I need to round the decimal to the last to decimal points, so t wouldnt be 5 it would be 5.00, and not 5.0 but 5.00, and if it 1-9 it needs a 0 infront of it so like 5.00 would need to be 05.00 and just 5 would neet to be 05.00.

2. I need another one that will round to the last 2nd plast digit. The only trick in this one is that if its 3.2422 usually that would roung too 3.24 I need it to round too 3.25.

Get It?

Thanks in Advance
Andrew.

Well I was playing around with this, so I figured I might as well post what I came up with

<?

$number = "5";

$length = strlen($number);

if ($length < 4) {
   $exploded = explode(".", $number);
   $exploded[0] .= ".00";
   $rounded = $exploded[0];
} else {
   $rounded = round($number, 2);
}

echo $rounded;


?>

To display 5.00 as 05.00

do this
$number = 5.22;
printf("%02.2f",$number);

%02.2f means printing a float number in the 00.00 format.
putting a %02.2 instead of %2.2 differs in that the

%2.2f will print " 5.22" <- notice the space infront
and
%02.2f will print "05.22"

To round to the next higher number.
u can just add 0.005 to the value

$info = 0.0243;
$info += 0.005 //becomes 0.0248
when u round it it will become the bigger number.

echo round($info,2) will print 0.025 without any problem

Those two work great, now what would I do if all I wanted to do was make sure the first number started with two letters except for 0 example:

1.013 = 01.013
141 = 141.00
.51 = 0.51

So this is what I need

If the number goes over the second decimal place, leave it.

I believe you have to be clearer in your request in your example. I don't get you sorry.
