JSON Path string to number

[markfree]

Using preprocessing, I'm trying to read some JSON data from a service and it is returning me a string instead of a number.

The JSON is similar to this:

{
"nodes": {
"rHhmEKJNSMmpcV9p5my2CQ": {
"timestamp": null,
"name": "",
"transport_address": "",
"host": "",
"ip": "",
"roles": null,
"attributes": {},
"indices": {},
"os": {
"timestamp": 1655814297289,
"cpu": {
"percent": 19,
"load_average": {
"1m": 2.08,
"5m": 2.16,
"15m": 2.14
}
}
}
}
}
}

I want to extract the load_average for 1m, so I'm using this JSONPath:

$.nodes.*.os.cpu.load_average.1m

With this path I can reach the correct value, but it happens to be a string.
Instead of receiving 2.08 number, I'm getting [2.08] string (with brackets).
Therefore, my item gets unsupported.

Is there a way to convert this string to a number using JSONPath?

There was a similar thing just recently...
use "$.nodes.*.os.cpu.load_average.1m.first()"
