Camunda rest engine json number as BigDecimal

BPMN & Modeling Discussion & Questions

I’ve downloaded the camunda bpm platform in order to evaluate dmn decisions by using the rest api.

For that I deploy this decision table:

dmn_double_sum

And send this json request:

{
    "variables":
    {
        "a": {
            "value": 100.01
        },
        "b": {
            "value": 10.01
        }
    }
}

I receive the following response:

[
    {
        "result": {
            "type": "Double",
            "value": 110.02000000000001,
            "valueInfo": {}
        }
    }
]

I expect that the value of “result” were “110.02” but instead it gives “110.02000000000001”. The issue is that camunda “engine-rest” receives numbers as “Double”, so by making a sum it looses precision.

It’s there a way for making camunda “engine-rest” receives numbers from json as “BigDecimal” instead of “Double” in order to not loose precision?.
