<pre>
    Example program `test/float.h`:
```c
float f = 0.1;
```

Correct (simplified) non json ast dump (`clang -x c++ -Xclang -ast-dump -fsyntax-only test/float.h`):
```
    `-FloatingLiteral 0x1e94648 <col:11> 'double' 1.000000e-01
```

Wrong (simplified) json ast dump ( clang -x c++ -Xclang -ast-dump=json -fsyntax-only test/float.h`):
```json
{
          "inner": [
            {
              "id": "0x1511648",
              "kind": "FloatingLiteral",
              "range": {
                "begin": {
                  "offset": 10,
                  "col": 11,
                  "tokLen": 3
                },
                "end": {
                  "offset": 10,
                  "col": 11,
                  "tokLen": 3
                }
              },
              "type": {
                "qualType": "double"
              },
              "valueCategory": "rvalue",
              "value": "0.10000000000000001"
            }
          ]
        }
      ]
    }
  ]
}
```

Float values with more than 1 digit after the decimal point do not show this problem.
