Add up Numbers to get Duration

[Fabian_Weller]

I have 2 Number type columns that represent minutes.
[Number_1] and [Number_2]
The max value of each column is 60.
In a Virtual Column I want to add up these 2 values to get a Duration type.
[Number_1] or [Number_2] can be empty.
I want to ignore seconds.

What is the best way?
This is what I’ve done:

TIME("00:"&(0+[Number_1]))-"00:00"
+
TIME("00:"&(0+[Number_2]))-"00:00"

Looks good to me!
