If you use a double instead of a float then it's going to work as you expect: 

PUT test 
{
  "mappings": {
    "doc": {
      "properties": {
        "total": {
          "type": "float"
        },
        "total2": {
          "type": "double"
        }
      }
    }
  }
}

PUT test/doc/1
{
  "total": 99999999999,
  "total2": 99999999999
}

POST test/_search 
{
  "size": 0,
  "aggs": {
    "total": {
      "sum": {
        "field": "total"
      }
    },
    "total2": {
      "sum": {
        "field": "total2"
      }
    }
  }
}

Results =>

{
  "aggregations" : {
    "total" : {
      "value" : 9.9999997952E10
    },
    "total2" : {
      "value" : 9.9999999999E10
    }
  }
}
