Hello everyone,

I have a CNC reporting some torque data using OPC UA. The problems is that the data format(?) is in Float64Array and the reported value (debugging) shows double quotes. How do I convert this to a usable number(no double quotes nor Float64Array) ? I'll be sending this numeric value to InfluxDB eventually.

It behaves just like a regular array, no conversion needed. You can access the first element with `msg.payload[0]`.

> The Float64Array typed array represents an array of 64-bit floating point numbers (corresponding to the C double data type) in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0....
