Hi There,

I'm just playing around with @cymplecy [inhouse mqtt broker](https://discourse.nodered.org/t/fun-exercise-make-an-mqtt-broker-in-node-red/82229) and came across the switch at the front which contains binary and hexadecimal values in a number field:

When I use an inject node to generate those values, I get a format error:

but no errors on the edit panel:

I tried using the buffer type for those values but got a JSON parse error:

 ![Screenshot 2025-07-05 at 19.06.12](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/7/37e369239691604e9fe4b887c9169a68f5dcfbb2.png)

How is that the number field in the switch node supports a different set of values to the inject node - what am I missing?

The nodes in questoin:

```flows
[{"id":"ce8a0e2105861dc1","type":"inject","z":"dc897f402c53697f","name":"","props":[{"p":"fuar","v":"0b00110000","vt":"num"},{"p":"ff","v":"0x82","vt":"num"},{"p":"gg","v":"0xC0","vt":"num"},{"p":"hh","v":"0b10100010","vt":"num"},{"p":"jjj","v":"0b11100000","vt":"num"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":848,"y":1133,"wires":[["943d8187afdbd94d"]]},{"id":"f3500f36eed92063","type":"switch","z":"dc897f402c53697f","name":"Test packet type","property":"payload.0","propertyType":"msg","rules":[{"t":"eq","v":"16","vt":"num"},{"t":"eq","v":"0xC0","vt":"num"},{"t":"gte","v":"0b00110000","vt":"num"},{"t":"eq","v":"0x82","vt":"num"},{"t":"eq","v":"0b10100010","vt":"num"},{"t":"eq","v":"0b11100000","vt":"num"},{"t":"else"}],"checkall":"true","repair":false,"outputs":7,"x":903,"y":1255,"wires":[[],[],[],[],[],[],[]]},{"id":"943d8187afdbd94d","type":"debug","z":"dc897f402c53697f","name":"debug 437","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":1142,"y":1157,"wires":[]}]

Please raise an issue if something valid is being flagged as an error

Done.

BTW you are going to support having binary and hexadecimal values in the inject node right? I mean you're not going to add an error in the edit panel?
