       * Sum of the values of the requested field.
       *
       * * Only numeric values will be aggregated. All non-numeric values
       * including `NULL` are skipped.
       *
       * * If the aggregated values contain `NaN`, returns `NaN`. Infinity math
       * follows IEEE-754 standards.
       *
       * * If the aggregated value set is empty, returns 0.
       *
       * * Returns a 64-bit integer if all aggregated numbers are integers and the
       * sum result does not overflow. Otherwise, the result is returned as a
       * double. Note that even if all the aggregated values are integers, the
       * result is returned as a double if it cannot fit within a 64-bit signed
       * integer. When this occurs, the returned value will lose precision.
       *
       * * When underflow occurs, floating-point aggregation is non-deterministic.
       * This means that running the same query repeatedly without any changes to
       * the underlying values could produce slightly different results each
       * time. In those cases, values should be stored as integers over
       * floating-point numbers.
