Problem Description

When using scaled_float, there is no range check on the value and scaling factor to be outside the long value range.

According to documentation for scaled_float:

scaled_float - A floating point number that is backed by a long, scaled by a fixed double scaling factor

However, that assumption is not checked on document ingestion. The following mapping:

"properties": {
"a_scaled_float": {
"scaling_factor": 1000000,
"type": "scaled_float"
}
There's a scaled_float mapping configuration with value 1000000.
So, why did the number 1707339753294418 become 9223372036854.775? Shouldn't it be 1707339753294418000000?

{
"_index": "test-index",
"_id": "Z5t_iY0BLRoRMvLbP6e3",
"_score": 1,
"_source": {
"a_scaled_float": 1707339753294418
},
"fields": {
"a_scaled_float": [
9223372036854.775
]
}
}

This is due to the rounding up done here, which produces a long value which is outside range, and thus returns MAX_LONG.

As this provides an incorrect result, and the value is outside of the long range, the correct behaviour should be to error on the value as other numeric types do.

Steps to Reproduce

Set a mapping with properties:

PUT test-index
{
      "mappings": {
        "properties": {
            "scaled_float": {
              "type": "scaled_float",
              "scaling_factor": 1000000
            }
        }
      }
}

Ingest a document:

PUT test-index/_doc/1
{
  "scaled_float": 1707339753294418
}

This should return an error, as the number is outside the long range.
