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 in another node, [[actionName:result]] is the variable name you should use. If successfully calculated, a "Yes" result is returned, else a "No" result is returned.

Examples

The table below describes 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
