Add documentation on tooltip float preciesion

[DrBlokmeister]

This morning I spent over 30 minutes trying to find out how to change the float precision of a tooltip. I have the float precision set to 0 on all possible options, but still the tooltip sometimes displayed 10 decimal places! I use rounding, so I this amount of decimals is not surprising. However, it is not helpful for the overview.

Please add a line on documentation or an example on how to do rounding in the tooltip, and a usecase.

This is my usecase, if that is useful:

    - type: custom:apexcharts-card
      graph_span: 24h
      update_interval: 1m
      all_series_config:
        float_precision: 0
      apex_config:
        plotOptions:
          pie:
            donut:
              labels:
                show: true
                total:
                  show: true
                  label: Total
                  formatter: |
                    EVAL:function(w) {
                      return Math.round((w.globals.seriesTotals.reduce((a, b) => {return (a + b)} , 0)).toFixed(2)) + ' W';
                      }
                value:
                  show: true
                  formatter: |
                    EVAL:function(val) {
                      return Math.round(val) + ' W'
                    }
      chart_type: donut
      series:
        - entity: sensor.electricity_meter_power_consumption_phase_l1
          name: Phase 1
          transform: "return Math.round(x * 1000);"
          unit: W
          group_by:
            func: avg
            duration: 1min
        - entity: sensor.electricity_meter_power_consumption_phase_l2
          name: Phase 2
          transform: "return Math.round(x * 1000);"
          unit: W
          group_by:
            func: avg
            duration: 1min
        - entity: sensor.electricity_meter_power_consumption_phase_l3
          name: Phase 3
          transform: "return Math.round(x * 1000);"
          unit: W
          group_by:
            func: avg
            duration: 1min
