Numberbox format to 5 or 5.1 not 5.0 [SOLVED]

[dayaners]

Good day, I would use the number box to create student grades in high school, however the number rounds to integer. Need to be allowed to place or integer (5) when he put the precision 2 rounds (5.0) but I need to stay (5) or (5.2).
Could someone help me? sorry for my bad english.

Code:

 {field:'ano1',title:'ANO 1',width:70,align:'center',editor:{type:'numberbox'}},

The numberbox takes the 'precision' property that can be used to display the number precision after the decimal separator.

Code:

{field:'ano1',title:'ANO 1',width:70,align:'center',
  editor:{
    type:'numberbox',
    options:{
      precision:1
    }
  }
},

when  i put precision 1:

the value 5.1 stay 5 and when put 5.5 they go to 6...

i need put 5.1 or 5.2 and 5 only

If you want to do some special conversions, you have to customize the 'formatter' and 'parser' functions. The code below achieves how to round a number downwards to the nearest integer.

Code:

{field:'ano1',title:'ANO 1',width:70,align:'center',
  editor:{
    type:'numberbox',
    options:{
		formatter:function(v){
			return v;
		},
		parser:function(s){
			var v = parseFloat(s);
			return isNaN(v)?'':Math.floor(v);
		}
    }
  }
},

this is the default, I need it to stop rounding.

got thanks a lot!

Code:

{field:'ano1',title:'ANO 1',width:70,align:'center',editor:{type:'numberbox',options:{
				formatter:function(v){
				return v;
				},
				parser:function(s){
					var v = parseFloat(s);
					return isNaN(v)?'':Math.abs(v);
				}}}
			}
