[boris_ph]

Hi,
I have a decimal value , such as : 12345.670000
I only want to echo 12345.67 without display 0
How can I do that?
Somebody can helps me?

Are you saying you want to display all decimal values as normal floating-point numbers without the trailing 0's? If so, just typecast it to a foat:

$value = (float)$value;

yup!
I wish to display the value in floating-points number without tailing the 0s.
i'm using php5, tried to display it by

$value = (float)$value;

but it failed.

one of my methods is using round() function.since i don't want the 0s.i try to do so:

$value=12345.670000;
$value=round($value,2);
echo $value;

// answer: 123456.67

Is there any method to display the $value besides using round() function??
let say, if the $value = 12345.675000 yet i jz want to display it until .67 but not 5 without round it..
somebody got any idea?
or i need to covert it into string and use substr() function and limit the length of string to display it?any other better way? 🙂

You could try [man]sprintf/man.

<?
function cutzero($value) {
return preg_replace("/(.\d+?)0+$/", "$1", $value)*1;
}
?>

Some examples:

<?
cutzero("4.7600"); // returns 4.76
cutzero("4.7604") // returns 4.7604
cutzero("4.7000"); // returns 4.7
cutzero("4.0000"); // returns 4
?>

// this function not bad..but only can cut off the '0' .hehe
