Great work!

@anur7 @nunesanderson Implemented as it is, it's going to fail.
You are importing a method that is in the pyaedt-examples repo and the user does not install the package in the venv that is using to run the example. In the venv there will be only pyaedt (ideally).
I think this method should not be part of the examples repo but rather in pyaedt.

@gmalinve is right.

This could be a new file in PyAEDT, if it is something we do not expect users to use it could be implemented here:

https://github.com/ansys/pyaedt/tree/main/src/ansys/aedt/core/internal

or if it is something useful to be exposed:

https://github.com/ansys/pyaedt/tree/main/src/ansys/aedt/core/generic

@Samuelopez-ansys I guess we can reuse this one from PyAEDT: https://github.com/ansys/pyaedt/blob/d7025d55af2978fa5a66504eda6fd3bdaf2a0309/src/ansys/aedt/core/generic/numbers_utils.py#L400 as @eblanco-ansys pointed out.
