el-保留小数点 toFixed()

//计算检查项目总金额
const math_total_price = () => {
  state.total_price = 0;
  for (let i = 0; i < state.check_request_table.length; i++) {
    state.total_price =
      parseFloat(state.check_request_table[i].tech_price) + state.total_price;
  }
  // toFixed() 方法可把 Number 四舍五入为指定小数位数的数字
  state.total_price = state.total_price.toFixed(2);
};
