I have this PHP code:

$entityElementCount = (-($highScore-$totalKeywordCount))/0.29;

What i want to know is, how to check whether $

Answer 1

Just to share my solution with localized string/number, this combo worked like a charm for me.

public static function isWholeNumber ($input, $decimalDelimiter = ',')
{
    if (is_string($input)){
        $input = str_replace($decimalDelimiter, '.', $input);
        $input = floatval($input);
    }

    if (fmod($input,1) !== 0.0) {
        return false;
    }

    return true;
}
