Calculate
The Calculate action node allows you to perform mathematical operations on flow variables.
You can use two types of mathematical operations:
Comparison: variables are compared against each other as per the expression - if it matches, a 'Yes' result is returned, if it doesn't match, a 'No' result is returned.
Calculation: the result of the expression is calculated and stored under a session variable [[actionName:result]] - in other words, if you want to refer to the result of this calculation, that is the variable name you should use. If successfully calculated, a 'Yes' result is returned, else a 'No' result is returned.

The below table describes some examples of mathematical expressions you can define in Chat Flow. You can create expressions as simple or complex as required.
Description | Example | ​ |
+ - / * | Standard math calculations (add, subtract, divide, multiply) | a+b, a-b, a/b, a*b |
= > < >= <= | Standard comparison operators (equals to, greater than, less than, greater than or equals to, less than or equals to) | a=b, a>b, a<b, a>=b, a<=b |
!= | Not equal to comparison operator | a!=b |
