[SOLVED] Moving the decimal two places over.

[pocobueno1388]

I have a number that looks like this:

0.014

 

I am trying to:

• Move the decimal two places to the right
  
• and delete any 0's at the beginning of the number.

 

How could I accomplish this? This is as far as I got:

 

<?php

$num = "0.014";

//find where the decimal is in the number
$find_decimal = strpos($num, ".");

//where the decimal should be [2 places to the right]
$decimal = $find_decimal+2;


?>

 

Now I'm just lost of what to do....any help is greatly appreciated, Thanks

try this m8

 

http://uk2.php.net/number_format

[xyn]

$num = 0.014;

number_format($num, 0, ".");

[pocobueno1388]

$num = 0.014;

number_format($num, 0, ".");

 

That gives me an error:

 

Warning: Wrong parameter count for number_format() in ..... on line 4

I'm not sure that number_format() will move the decimal...

Well, I just found a nice function on PHPfreaks:

 

<?php

function move_decimal($number,$direction,$places = 1) {
  if($direction == 0) {
    $number = $number * pow(10, ($places * -1));
  }
  if($direction == 1) {
    $number = $number * pow(10, $places);
  }	
  return $number;
}

?>

 

So  let me try this, and I will report back if I got everything working.

number_format() will move the decimal.

i used it in my rating system.

Well the function worked perfect =]

 

Thanks for the help ^^

the number format function is correct ok.

 

<?php

$number = 1234.5678;

$english_format_number = number_format($number, 2, '.', '');

ECHO $english_format_number;
?>
