How to render a svg circle using start and endAngle

I have rendered the svg circle using start and endAngle. It was worked fine. But when i render the complete circle(startAngle as 70 and endAngle as 70) the output is huge different(except the 0, 90, 180, 270). what i made wrongly for this code?

            function getPathArc(center, start, end, radius) {
                end -= this.isCompleteAngle(start, end) ? 0.0001 : 0;
                var degree = end - start;
                degree = degree < 0 ? (degree + 360) : degree;
                return this.getCirclePath(
                    center, getLocationFromAngle(start, radius, center),
                    getLocationFromAngle(end, radius, center), radius, (degree < 180) ? 0 : 1
                );
            }

            function getCirclePath(center, start, end, radius, clockWise) {
                return 'M ' + start.x + ' ' + start.y + ' A ' + radius + ' ' +
                    radius + ' 0 ' + clockWise + ' 1 ' + end.x + ' ' + end.y;
            }

            function getLocationFromAngle(degree, radius, center) {
                var radian = (degree * Math.PI) / 180;
                return {
                    x : Math.cos(radian) * radius + center.x,
                    y : Math.sin(radian) * radius + center.y
                }
            }

            function isCompleteAngle(startAngle, endAngle) {
                var totalAngle = endAngle - startAngle;
                totalAngle = totalAngle <= 0 ? (totalAngle + 360) : totalAngle;
                return Math.floor(totalAngle / 360) !== 0;
            }

The Green circle is rendered correctly because the start and endAngle is 90 even if i change the angle as 0, 180, 270 and 360 it will work. but The actual problem is Red circle which i use 70 even the issue will come except those angles(0, 90, 180, 270, 360).

how to clear this issue?
