我的页面滑块上出现此错误:

警告:number_format()期望参数1为double,第30行的/home/globalar/public_html/wp-content/themes/automotive_s1/includes/slider.php中给出了字符串

<?php

    if $str = floatval($str); ($post->post_type == "gtcd") {
        the_title();
    if (isset( $fields['price'])) {
        echo ' | <span class="price_slider">'.'  '.$symbols['currency']; 
        echo number_format($fields['price']).'</span> ';
    } else { 
        echo '';
}
