JSON parsing removes decimal trailing zeros

I have a Json string, after parsing I want it to remain in decimal form.

import play.api.libs.json._

val jsonString = """{"value":2.0}"""

println(jsonString)
println(Json.parse(jsonString))

The output of the code above is:

{"value":2.0}
{"value":2}

I need it to be

{"value":2.0}
{"value":2.0}
Solution

  • play-json created an option to preserve zero decimals

    https://github.com/playframework/play-json/pull/831/files

    Just add -Dplay.json.serializer.preserveZeroDecimal=true to VM options.
