"gettype()" function in KQL - "double" result

How about this:

- Normalize the output: You can write a wrapper function or conditional logic that maps "double" to "real" before processing.
- Raise a documentation request: You're spot-on, Microsoft should either:
- Normalize gettype() to always return "real" for doubles, or
- Explicitly mention "double" as a possible return value in the docs.

let type = gettype(cm.total);
case(
    type == "double", "real",
    type == "long", "long",
    type == "string", "string",
    "unknown"
)
