Good idea Otto. I always thought there should be a better way to deal with the decimal than the manual entry. I think I will incorporate something similar.

A somewhat simpler approach:


if ((1 / $imagemeta['image_meta']['shutter_speed']) > 1) {
	echo "1/";
		if (number_format((1 / $imagemeta['image_meta']['shutter_speed']), 1) ==  number_format((1 / $imagemeta['image_meta']['shutter_speed']), 0)) {
			echo number_format((1 / $imagemeta['image_meta']['shutter_speed']), 0, '.', '') . ' sec';
		} else {
			echo number_format((1 / $imagemeta['image_meta']['shutter_speed']), 1, '.', '') . ' sec';
		}
	} else {
		echo $imagemeta['image_meta']['shutter_speed'].' sec';
	}

Basically I compare the 1 decimal version to the 0 decimal version. If they're equal, then the final digit is zero and you can display it with no decimal. If they're different, the final digit is not zero, so display it. This solves your 1.3, 1.5, 1.6, etc problem without checking for them manually.

This works for me:



function decimal2fraction ($number)

{

    list ($whole, $numerator) = explode ('.', $number);

    $denominator = 1 . str_repeat (0, strlen ($numerator));

    $GCD = GCD ($numerator, $denominator);

    $numerator /= $GCD;



    $denominator /= $GCD;

    if($whole == 0)

        return sprintf ('1/%d', round($denominator/$numerator));

    return sprintf ('%d 1/%d',

        $whole, round($denominator/$numerator));

}



function GCD ($a, $b)

{

    while ( $b != 0)

      {

        $remainder = $a % $b;

        $a = $b;

        $b = $remainder;



      }

    return abs ($a);

}

Thank you! I was about to do something just like this myself, but thought I should check the comments on Sarah’s post in case someone already had. You saved me much time and musings on how I wanted to do it!

Thank you for sharing this! I just got a Nikon SLR camera yesterday and have planned on trying to show this information as soon as I got a new camera. I’m going to try and see if I can get the full size dimensions to show up like Matt has on his site, but your setup is exactly what I was looking for. Thank you again!
