Formating the number

[shivani.shm]

I have a number as $num = '10.667' and i wnt the output as 10.66 . I tried using sprintf it gives me the output as 10.67

can anyone tell me how to do it..

 

thanks in advance.....

you want to use a floor function it looks like as you want to round down it appears however floor only returns whole integers, so what you will need to do is somethign a bit fancier

try

<?php
function dec_floor($int){
$tmp = explode(".",$int);
$ret = $tmp[0].".".substr($temp[2],0,2);
return $ret;
}
?>

thanks your code is wrking ...

but is this the only way...

is there any build in function which will directly output me 10.66 if i give 10.667 as the input...

i m not interested in rounding the number just wnt it upto two decimal places....

 

thanks in advance....

if sprintf or number_format (http://us3.php.net/manual/en/function.number-format.php)

don't do it then yes this is the way.  It isn't going to hinder your speed and will always return a number with its full left side of the decimal with the right side stripped to 2 places (if its less than 2 it shows the . and what is there if nothign just a point)

try this

 

<?php
$intNum = 10.667;

echo ((int) ($intNum*100))/100;
?>

<?php
$num = '10.667';
$formatted = sprintf("%01.5s", $num);
die("Formatted: $formatted");

try with this number .... it's not showing properly ........ $num = '129.99889';

 

[PHP_PhREEEk]

He didn't say the number changes format, and only gave one example format. The sprintf provided returns 5 characters, including the decimal point. I would hope the OP could easily modify the code to accomodate any number of characters to the left of the decimal...

food for thought

 

<?php
$intNum = 129.3333;


function number_cut($intNum,$intCut)
{
return ((int) ($intNum*('1'.str_repeat('0',$intCut))))/('1'.str_repeat('0',$intCut));
}

echo number_cut($intNum,1)."<BR>";
echo number_cut($intNum,2)."<BR>";
echo number_cut($intNum,3);

?>

His starting number is a string, not a float, and he asked for a built-in function within PHP... are we providing the solutions or just trying to impress the gallery?

well in PHP that would not matter as it type juggles, so you can specify it as a string the result would be the same. impress the gallery!! not at all

[cooldude832]

as you can see there are a ton of ways to do it

I did it as a string

The second version was as a nubmer

and now again as a string

 

The madness will never stop!
