wx.chooseLocation获取的经纬度开发工具和真机调试的位数不一？获取经纬度位数怎么控制？

   wx.chooseLocation({
      success: function (res) {
        let longitude="viewlists.longitude"
        let latitude="viewlists.latitude"
        let address="viewlists.address"
          that.setData({
            [longitude]: res.longitude,
            [latitude]: res.latitude,
            [address]: res.address,
          })
          wx.showToast({           
            title: '已完成坐标获取',
            icon: 'none',
            duration: 1500//持续的时间
          })
      },
      fail(res) {
        wx.showModal({           
          title: '错误',
          content: '请重新获取位置',
          showCancel: false
        })
      }
    })
