@spmallette yes, maybe some code will help explain.
```
ObjectMapper mapper =
GraphSONMapper.build().version(GraphSONVersion.V2_0).typeInfo(GraphSONMapper.TypeInfo.PARTIAL_TYPES).create().createMapper();
Map<String, Integer> map = new HashMap<>();
map.put("helo", 2);
String s = mapper.writeValueAsString(map);
// prints 's = {"helo":2}'
System.out.println("s = " + s);
Map read = mapper.readValue(s, Map.class);
// prints 'read.get("helo") = class java.lang.Integer'
System.out.println("read.get(\"helo\") = " +
read.get("helo").getClass());
Map<String, Long> map3 = new HashMap<>();
map3.put("helo", 2L);
String s2 = mapper.writeValueAsString(map3);
// prints 's2 = {"helo":[{"@class":"Long"},2]}'
System.out.println("s2 = " + s2);
Map read2 = mapper.readValue(s2, Map.class);
// prints 'read2.get("helo") = class java.lang.Long'
System.out.println("read2.get(\"helo\") = " +
read2.get("helo").getClass());
```
> number with decimal and no type = Java Float
Almost, by default decimals are Double, not Floats.
