Range node out of bounds?

Core Development

Hi There,

Just a quick heads up - the range node can be brought to generating values outside of the configured bounds:

[
    {
        "id": "9b95f8806d032b1a",
        "type": "inject",
        "z": "ae38b2dbd23d1681",
        "g": "b4012d193105c803",
        "name": "",
        "props": [
            {
                "p": "payload"
            }
        ],
        "repeat": "",
        "crontab": "",
        "once": false,
        "onceDelay": 0.1,
        "topic": "",
        "payload": "13.1",
        "payloadType": "num",
        "x": 627,
        "y": 1175,
        "wires": [
            [
                "9867b9610c1786d5"
            ]
        ]
    },
    {
        "id": "9867b9610c1786d5",
        "type": "range",
        "z": "ae38b2dbd23d1681",
        "g": "b4012d193105c803",
        "minin": "0",
        "maxin": "9.5",
        "minout": "0",
        "maxout": "100.5",
        "action": "clamp",
        "round": true,
        "property": "payload",
        "name": "",
        "x": 954,
        "y": 1175,
        "wires": [
            [
                "4fbf1055ffadffe5"
            ]
        ]
    }
]

Range node is configured to target range of 0 - 100.5 and the value 13.1 is outside of the incoming range of 0 - 9.5, range node is configured to "limit to the target range".

This example will give a value of 101 because I also set the "round result to the nearest integer".

But the value should really be 100 since that's within the target range.

Btw doing the same test but with negative values works, i.e. target range of 0.5 to 100.5 and using a negative values gives 1 not 0, e.g.:

[{"id":"9d47e88afa90b312","type":"inject","z":"ae38b2dbd23d1681","g":"b4012d193105c803","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"-13.1","payloadType":"num","x":784,"y":1231,"wires":[["a9b9805029fecc58"]]},{"id":"a9b9805029fecc58","type":"range","z":"ae38b2dbd23d1681","g":"b4012d193105c803","minin":"0","maxin":"9.5","minout":"0.5","maxout":"100.5","action":"clamp","round":true,"property":"payload","name":"","x":1121,"y":1231,"wires":[["eb733ddd81f3ed5a"]]}]

but will give zero if the start value is zero.
