    //          note 1: The native parseFloat() method of JavaScript returns NaN
    //          note 1: when it encounters a string before an int or float value.
    //       example 1: floatval('150.03_page-section')
    //       returns 1: 150.03
    //       example 2: floatval('page: 3')
    //       example 2: floatval('-50 + 8')
    //       returns 2: 0
    //       returns 2: -50
    return parseFloat(String(mixedVar ?? '')) || 0;
