formatting floating-point like .xxx 2

[Shrp]

I have a php script that prints out a floating point value that I would like to format with three positions after the decimal point, but no leading zero.

So I'd like a combination of printf ("%0.3f",$var) and ltrim($var,0), but printf ("%0.3f",ltrim($var,0)) seems to ignore the 'ltrim' part.

So for $var = 1, I'd like to output 1.000, for $var = 1/2 -> .500, $var = 1/3 -> .333, etc. Thanks!

Here's one solution:

<?
$vars = array(1,.5,1/3);
foreach ($vars as $var)
  echo ltrim(sprintf("%0.3f",$var),0)."\n";
?>

What you tried:

printf ("%0.3f",ltrim($var,0))

does the ltrim before the formatting. My code, does the ltrim after the formatting.
