Global variable in numeric format

[wmarcolin]

I would like an explanation of how I can define a global variable in numeric format.

Scenario 1:

• Create a global variable in Expressions > Add Expression > variable name > set initial value = 0 (number zero)
• When entering Rule Sets > Triggers > Variable Value, the variable created appears to be selected and used in the rule
• However, in Set Reaction > Set Variable, this variable that was created with a numeric value does not appear, so we cannot change the value.

Scenario 2:

• Create a global variable in Expressions > Add Expression > variable name > DO NOT SET VALUE, leave as null
• When to go into Rule Sets > Triggers > Variable Value, the variable created appears to be selected and used in the rule, of course, because it has no value yet it is set to zero
• In Set Reaction > Set Variable, this variable appears, and we can define a content, that even if it is a number, it will be stored as a character

To summarize, for scenario 1, I can't find a way to handle the value. For scenario 2, it works, but I can't use it if I want to use the variable for mathematical operations.

A little help from the community.

I use MSR 21153.

Thanks

Scenario 1 if you delete the varset rule and tehn the global varible disappears from the drop down list, If you delete the global var and then re-add it it appears back in list for set variable.. This seems to be a bug

I can not see the issue in scenario 2 as i can make calculations and get them as integers.

You cannot Set Variable on a variable that has an expression. Expression-driven variables can only have expression results.

If you supply a constant as the value for Set Variable, it will always be a string. To assign a number or any other type, use an expression:

• Set Variable testval = ${{ 0 }} — results in assignment of the number zero to the variable.
• Set Variable testval = ${{ null }} — set the special value null on the variable.
• Set Variable testval = ${{ ["fish","dog","cat"] }} — the variable gets an array

Whatever the result datatype of the expression in ${{ }} will be the data type assigned to the variable.

Teacher @toggledbits , thanks for the lesson, problem solved.
