I have used jqgride and i am facing a problem when i want to find avg of a column for Ex-

sumFloat19 = grid.jqGrid('getCol', 'Loadfactor', true, 'avg');

it will give values like 73.4965517241 but i want 73.49, so help me solve this problem.

my 2nd problem is i want pagination but not want to pass dynamic value, not like that      rowList:[100,200,300],

 

 

  $("#lstReport").jqGrid('setGridParam', {url:'<%=request.getContextPath()%>/indiconsreport.do?method=condIndividual&fromdate='+fromdate+"&todate="+todate+"&region="+region+"&depot="+depot+"&condid="+condid,
