I want google pie chart to show pieSliceText to be rounded whole number

I am using Google Pie Chart, I want to display round percentage value but it is not showing like that. Anyone, suggest me an idea to show rounded percentage value. My code looks like

 google.setOnLoadCallback(drawChart);
                    function drawChart() {
 var data = google.visualization.arrayToDataTable([
                            ['Members', 'Total Members'],
                            ['Members', 23],
                            ['Total Members', 41 - 23]
                        ]);
                    var options = {
                            width: 150,
                            height: 150,
                            chartArea: {
                                width: 150,
                                height: 150,
                                left: 10},
                            legend: {position: 'none'},
                            tooltip: {trigger: 'none'},
                            colors: ['#FEC240', '#FFFFFF'],
                            pieSliceText: 'percentage',
                            pieSliceTextStyle: {
                                bold: true,
                                fontSize: 16,
                                color: 'black'
                            },
                            enableInteractivity: false,
                            pieSliceBorderColor: "#DFE0E1"

                        };
var chart = new 
google.visualization.PieChart(document.getElementById('checkpie'));
chart.draw(data, options);

<div id="checkpie" ></div>
