Format footer values in ui-grid

The templates you had tried will work for the normal cell values but your are trying to get the template work on a aggregate value.

To get the aggregate value for the column inside a template you can use {{col.getAggregationValue()}} and add your format options.

Since you want to have two decimals this would be more like {{col.getAggregationValue() | number:2 }}

Also remember the template will be different if you have column filters enabled on the grid.

if you need the after decimal point to show two values then use custom template functionality in grid options

       {            field: 'ORGINAL_FUNC_AMOUNT',            displayName: 'CR A/C',            aggregationType: uiGridConstants.aggregationTypes.sum,            footerCellTemplate: '<div class="ui-grid-cell-contents" >Total: {{col.getAggregationValue() | number:2 }}</div>'        }

$templateCache.put('ui-grid/uiGridFooterCell',"<div class=\"ui-grid-cell-contents\" col-index=\"renderIndex\"><div>{{ col.getAggregationText() + ( col.getAggregationValue() CUSTOM_FILTERS ) }}</div></div>"  );

CUSTOM_FILTERS = footerCellFilter propertygrid.colDef[0].footerCellFilter = 'number:2'
