Divide?

[moiisam10]

Hello guys... Am here again maybe with a noob question.. but well am just triying to learn all possible.

I got a variable...

$lal = 4820.492

and i need to divie all in 2... like

$lal2 = 2410.246

I triyied with

$lal2 = $lal/2;
echo $lal2;

But i just get the first character. so its "2" , i triyed with explode but dont work or dont know, with number_format and i dont know how to make it work.. Thanks in advanced to all.

I get your expected result 2410.246

$lal = 4820.492;
$lal2 = $lal/2;
echo $lal2; // output 2410.246

Are your sure $lal is what you expect it is? What does  var_dump($lal);  return?

Well... Really i get the $lal with this.

$lal = $row[0]->nodeValue;

from curl.

Oh. This is from yesterday?

 

You cannot do math operations with numbers which are formatted. You need to remove the number formatting so its whole number

// remove number formatting
$lal = str_replace(',', '', $row[0]->nodeValue);

// now divide by 2
$lal2 = floatval($lal) / 2;
echo $lal2;

If you dont remove the formatting PHP will truncate the value before the comma, so only 4 will be divided by 2 this why the result is 2
