Not a Number for a integer (NaN)

[labmaster]

I want to assign NaN for integer in the case structure.

Normally, NaN is for floating number.

Transforming NaN to the integer value, the result is 2147483647(+MAX) for the I32 format.

In this stage, I don't know if the minimum or maximum value is used in my code.

How can I assign NaN for integer variable in a case structure?

Integers don't have NaN. All available bit patterns are used up for regular numbers.

you can convert the NaN into a boolean by the "Not a Number/Path/Refnum" primitive from the comparison palette and wire the output to the case structure.
