        if (fmod($value, 1) !== 0.00) {

It seems like $value can also be of type string; however, parameter $x of fmod() does only seem to accept double, maybe add an additional type check?

            return $value;
        }

        if (\in_array($value % 100, range(11, 13), false)) {
            return $value . 'th';
        }
        switch ($value % 10) {
            case 1:
                return $value . 'st';
            case 2:
                return $value . 'nd';
            case 3:
                return $value . 'rd';
            default:
                return $value . 'th';

    public static function normalize($value): string
    {
        if (!is_scalar($value)) {

The condition is_scalar($value) is always true.

            throw new \InvalidArgumentException('Value must be scalar.');
        }

        $value = (string)$value;
        $value = str_replace([" ", ","], ["", "."], $value);
        return preg_replace('/\.(?=.*\.)/', '', $value);
    }
