Notice: A non well formed numeric value

wp-config.php: When I set define( 'WP_DEBUG', true );
I received messages on pages with Syntax Highlighter:

Notice: A non well formed numeric value encountered in /home/…/wp-content/plugins/urvanov-syntax-highlighter/class-urvanov-syntax-highlighter-formatter.php on line 118

Notice: A non well formed numeric value encountered in /home/…/wp-content/plugins/urvanov-syntax-highlighter/class-urvanov-syntax-highlighter-formatter.php on line 119

The solution is here: https://kirkizh.ru/2018/02/php7-non-numeric-value
That worked for me:

118 $toolbar_height = (int)$font_size * 1.5 . 'px !important;';
119 $info_height = (int)$font_size * 1.4 . 'px !important;';
