calculate the ratio between the death and kills

Yo guys,

how could thy calculate a ratio between two things?
like the Kills and Death


??

You could subtract the deaths from the kills, or you could do what I do. A kill is worth 3 points and a death is worth 1 point.

You'd probably have to store the number of kills and deaths in a database of some type and constantly keep an updated number for the ratio (kills/deaths and maybe rounded to the tenths place)

How to have killed one gives 3 points? xD

I want to make it simple: p

PHP:

$points = $kills * 3 + $deaths;

Define the word ratio, and you would find that you are looking for kills divided by deaths. So $kills / $deaths of course.

PHP:

/**
 @param int $kills
 @param int $deaths
 @param int $digits default 3 decimal places

 @return string
 */
function getKdRatio($kills, $deaths, $digits = 3){
  if($deaths === 0) return "N/A";
  $ratio = (string) round($kills / $deaths, $digits);
  return rtrim($ratio, " 0.");
}

thank you !
