一些filter

    stringified
  let i = _int.length % 3

    (_int.slice(0, i) + (_int.length > 3 ? symbol : '')) :
    ''
  let _float = decimals ?
    stringified.slice(-1 - decimals) :
    ''
  let sign = value < 0 ? '-' : ''
  return sign + currency + head +
    _int.slice(i).replace(digitsRE, '$1,') +
    _float
})
Vue.filter('percent', value => { // 百分比

})
Vue.filter('FormatMoney', (value, hasDecimal) => { // 千位数字以上*代替

    } else {
