Description
hello!I'm having a problem
I used influx version 1.X and see write point storage type:
```
@SuppressWarnings("checkstyle:finalparameters")
@Deprecated
public Builder field(final String field, Object value) {
if (value instanceof Number) {
if (value instanceof Byte) {
value = ((Byte) value).doubleValue();
} else if (value instanceof Short) {
value = ((Short) value).doubleValue();
} else if (value instanceof Integer) {
value = ((Integer) value).doubleValue();
} else if (value instanceof Long) {
value = ((Long) value).doubleValue();
} else if (value instanceof BigInteger) {
value = ((BigInteger) value).doubleValue();
}
}
fields.put(field, value);
return this;
}
```
so insert data , All data will be converted to Double, InfluxDBResultMapper entity type must be Double
my dependency:
```
org.influxdb
influxdb-java
2.22
```
I want to use Mapper to convert to an entity Is there any other way I can use other types?

Research direction
Start with the deprecated Builder.field(String, Object) method and InfluxDBResultMapper, then trace how numeric field values are converted and mapped for the 2.22 dependency. Confirm whether mapping numeric fields to types other than Double is supported, and document or test the resulting behavior.
