DBGrid Column Float Round To 2 Decimal Places

[andyhill]

Without using an Editor can we round float columns to 2 decimal places ? If we have to use an Editor then I still need to round float value to 2 decimal places - Please show how to implement ?

Do we use something like this and how do we apply it in code:-

    applyValue: function(value) {
        value = parseFloat(value);
        if (isNaN(value) || value === null) {
            value = this.getDefaultValue();
        }

        //round the value to 1 decimal
        value = Math.round(value * 100) / 100;

        return this.callParent([value]);
    },

How do we use this in Delphi ?

editor: new Ed(new fm.NumberField({allowBlank: false,allowNegative: false,maxValue: 10, decimalPrecision: 3}))

My hidden panels are filled with hundreds of editors, there must be a better way.
