Limit characters in a custom field

    I have a custom field called “Summary”, which has content summaries of varying length. I need to cut off the text of this field at 150 characters on my index page so that the text doesn’t overflow. This is the code I’m using:

    if(!function_exists('summary_excerpt')){
	function summary_excerpt(){
		global $post;
		$trim_length = 150;  //desired length of text to display
		$summary_excerpt = 'Summary';
		$value = apply_filters('the_content', get_post_meta($post->ID, $summary_excerpt, true));
		if ($value) {
		  echo rtrim(substr($value,0,$trim_length)).'...';
		}
	}
}

    My issue is that the “…” prints even when my summaries are less than 150 characters, which looks really weird. Is there a way to indicate that the “…” following my summary excerpt should only display when the summary is longer than 150 characters?

    something like this (not tested):

    global $post;
$trim_length = 150;  //desired length of text to display
$summary_excerpt = 'Summary';
$value = get_post_meta($post->ID, $summary_excerpt, true);
if ($value != '') {
  if(strlen($value) <= $trim_length){
    echo apply_filters('the_content', $value);
  } else {
    echo apply_filters('the_content', rtrim(substr($value,0,$trim_length)).'...');
  }
}
