There is someone that could me explain why by this simple aggregation:

```auto
    > GET cfo1/_search
    > {
    > "size": 0,
    > "aggs": {
    > "NAME": {
    > "filter": {...},
    > "aggs": {
    > "somma": {
    > "sum": {
    > "field": "SommaDiOre_mens_Comm_CdC"
    > }
    > },
    > "aaa": {
    > "terms": {
    > "field": "SommaDiOre_mens_Comm_CdC",
    > "size": 12
    > }
    > }
    > }
    > }
    > }
    > }

```

I get this response with the sum that is not zero:

```auto
    > "aggregations" : {
    > "NAME" : {
    > "doc_count" : 11,
    > "aaa" : {
    > "doc_count_error_upper_bound" : 0,
    > "sum_other_doc_count" : 0,
    > "buckets" : [
    > {
    > "key" : -141.96,
    > "doc_count" : 1
    > },
    > {
    > "key" : -41.07,
    > "doc_count" : 1
    > },
    > {
    > "key" : -13.6,
    > "doc_count" : 1
    > },
    > {
    > "key" : -6.83,
    > "doc_count" : 1
    > },
    > {
    > "key" : -6.0,
    > "doc_count" : 1
    > },
    > {
    > "key" : 1.44,
    > "doc_count" : 1
    > },
    > {
    > "key" : 5.39,
    > "doc_count" : 1
    > },
    > {
    > "key" : 6.0,
    > "doc_count" : 1
    > },
    > {
    > "key" : 13.6,
    > "doc_count" : 1
    > },
    > {
    > "key" : 41.07,
    > "doc_count" : 1
    > },
    > {
    > "key" : 141.96,
    > "doc_count" : 1
    > }
    > ]
    > },
    > "somma" : {
    > "value" : 1.5987211554602254E-14
