/**
 *fix: doubleValue is rounded to integer.
 Short description: database stores double values without signs after dot.

 Scenario:
 Create datapoint on one of the instances.
 Record some daouble values into the datapoint: 0.1; 0.2; 0.3; 0.4 and so on.
 Read all values (for example Rest '/series' or from database: nimbits.valuestore).
 [Expected]: Values should be stored as double.
 [Actual]: Values are rounded to integer.
