json4s-spire is a collection of sane wrappers for basic spire number types to json4s Json AST representation, allowing you to easily decompose spire values to Json and extract Json values into spire values. It is built for scala 2.10 and scala 2.11.
Simply add the following dependency to libraryDependencies
"org.mdedetrich" %% "json4s-spire" % "1.3.0"
json4s-spire comes with 2 modes, withDouble and withDecimal. withDouble converts JDouble to relevant spire types and vice versa,
where as withDecimal converts JDecimal to relevant spire types and vice versa
The implicit val fixedScale is needed due to the spire FixedPoint type. If you need to change between different FixedPoints, you need
to create a different json4s Formats for each case
implicit val fixedScale = FixedScale(10)
val formats = DefaultFormats.withBigDecimal ++ org.json4s.spire.Serializers.withDecimalimplicit val fixedScale = FixedScale(10)
val formats = DefaultFormats.withBigDecimal ++ org.json4s.spire.Serializers.withDouble- More non trivial test cases need to be added
