The minimum and maximum of Integer types include a decimal point or use scientific E notation.

Hi. While building my Swagger instance from scratch, I import JSON Schemas using the syntax:

Model model = io.swagger.util.Json.mapper().readValue(jsonSchemaFile, Model.class);

I then create BodyParameters and Response objects and set these model instances on them.

I then serialize my Swagger instance to JSON using the following syntax.

Json.pretty().writeValue(swaggerFile, swagger);

The first problem I’m running into is that my Integer type minimum and maximum facets gain a decimal point (from somewhere).

Before (in JSON Schema file):

              "AccountCount":{
                 "type":"integer",
                 "maximum":9,
                 "minimum":0
              },

After (in Swagger file):

            "AccountCount" : {
              "type" : "integer",
              "minimum" : 0.0,
              "maximum" : 9.0
            },

The second issue I’m hitting is with decimal types where the bounds no longer come out right, and Swagger Editor complains about the use of scientific E notation for minimum and maximum.

Before (in JSON Schema file):

                            "Balance":{
                                "type":"number",
                                "format":"decimal",
                                "multipleOf":0.01,
                                "maximum":9999999999999999.99,
                                "minimum":-9999999999999999.99
                             } 

After (in Swagger file):

                      "Balance" : {
                        "type" : "number",
                        "format" : "decimal",
                        "minimum" : -1.0E16,
                        "maximum" : 1.0E16
                      }

Here’s another peculiar one where an Integer is expressed using scientific E notation.

Before (in JSON Schema file):

                             "AccID":{
                                "type":"integer",
                                "maximum":2147483647,
                                "minimum":-2147483648
                             },

After (in Swagger file):

                      "AccID" : {
                        "type" : "integer",
                        "minimum" : -2.147483648E9,
                        "maximum" : 2.147483647E9
                      },

I’ve attached the JSON Schemas and the serialized swagger doc. Thanks for any help!

I uplifted swagger-core to 1.5.11, but I still see the minimum and maximum values as decimals. Am I missing something here?

Hi. I changed Double to BigDecimal for the minimum and maximum facets of numerics in the relevant classes (AbstractNumericProperty, DecimalProperty.setExample, PropertyDeserializer) and configured the Json.mapper() with mapper.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS). With these changes the original decimal quantity that describes my minimum and maximum survive from deserialization of the JSON schema all the way to serialization of the Swagger model. I would like to commit the changes for review if that’s OK.
