4 byte (32 bit) Hex value to a floating point decimal number

[Somdev]

Hello,
Hope everyone is doing good.
I am new to Node-Red and I am looking for help. I am developing some flow to get data from an IO-Link sensor in Node-red and visualizing it in a graph in the dashboard. From the sensor, I am getting a 4-byte hex value and I need to convert it to a floating-point decimal number. I don't how to write the code for this function. Can anybody help me with it, please?

Thanks

maybe node-red-contrib-buffer-parser can help?

Alternatively, look at the nodejs Buffer object & its functions
