Yes, ACF returns number fields as strings.

Add a filter in functions.php

add_filter('acf/format_value/type=number', 'acf_number_str_to_number', 20, 3);
function acf_number_str_to_number($value, $post_id, $field) {
  if (empty($value)) {
    return $value;
  }
  $int = (int)$value;
  $float = (float)$value;
  if ($int == $float) {
    return $int;
  } else {
    return $float;
  }
}

You’ll need to contact the developers to change it any other way.
