public static final class AggregationQuery.Aggregation.Sum extends com.google.protobuf.GeneratedMessageV3 implements AggregationQuery.Aggregation.SumOrBuilder
 Sum of the values of the requested property.

 * 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.
