  //      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(mixedVar) || 0
