PHP append random number if value have only 1 number

Question

I am using a code to view the TMDB movie rating generally the rating of the movie is 3 characters for example: 7.4 but, many times the rating is only one character like for example 6.

I should add the value .4 or a random number with the dot only if the number is single and doesn't have 3 characters.

I am using a code on wordpress for the progress bar, the problem is that I need a multiple and not a single number I have to add a random number immediately after the single value, I haven't tried anything yet I don't know where to start — Vincenzo Piromalli

I would recommend just appending '.0' to the number when it only has a length of 1.

function getRating($value){
  return $value . (strlen($value) === 1 ? '.0': '');
}

But, if you must randomise it:

function getRating($value){
  return $value . (strlen($value) === 1 ? '.'.rand(0,9): '');
}

im using this code how to ad your function inside? function ProgressBar() { global $post; $vote_average = esc_html(get_post_meta($post->ID,'vote_average', true)); $progress = str_replace(".", "", $vote_average); $count = $progress; if ($count >= 0 && $count < 50) { echo 'danger'; } elseif ($count < 70) { echo ''; } elseif ($count < 80) { echo 'success'; } else { echo 'success'; } }

add it below/outside of your current function and call it inside where you need it.
