Just write a helper function that casts it yourself:

double numeric(JSONValue v) {
    if(v.type == JSON_VALUE.FLOAT)
         return v.floating;
    else if(v.type == JSON_VALUE.INTEGER)
         return v.integer;
    else if(v.type == JSON_VALUE.UINTEGER) // I think it has this 
too
         return v.uinteger;
    throw new Exception("not a numeric type, instead: " ~ 
to!string(v.type));
}


and then you should be able to do

jj.object["floats"].array[1].numeric.writeln;

and have it return float regardless of if it is 1 or 1.0
