Operators are used to specify comparisons between expressions.
Yeeflow offers various types of operators. This article lists operators supported by Expression Editor.
Overview of Operators
Please Note: You need choose the corresponding element(s) when using operators.
Operators  Description  Example  Outcome 
+
(Plus or string concat)  Plus two numbers for addition; or concat both elements(numbers and text).  [number1/Text1]+[number2/Text2]
E1. 1+3;
E2. 1+abc
E3. a+xy  E1. 4
E2: 1abc
E3. axy 

(Minus)  Minus number(s) for subtraction.  [number1][number2]
31  2 
*
(Multiply)  Multiple numbers for multiplication.  [number1]*[number2]
3*4  12 
/
(Divide)  Divide by sign for division  [number1]/[number2]
15/3  5 
%  Return the remainder(modulus) after a division of one number by another.  [number1]%[number2]
8%5  3 
(
(Open paren)  Open parenthesis.
It must consist of open parenthesis and close parenthesis.  3*(5+3)  24 
)
(Close paren)  Close parenthesis.
It must consist of open parenthesis and close parenthesis.  3*(5+3)  24 
And  Returns TRUE if all of its arguments are TRUE.
Mostly it's used between expressions.  E1: 7 > 0 and 5 > 3;
E2: variable 1==ABC and variable 2>500  E1: "Yes" or "Ture";
E2: "No" or "False"
[Assumed that variable 1 is "ABD", variable 2 is "800".] 
Or  Returns TRUE if any argument is TRUE.
Mostly it's used between expressions.  E1: 7 > 0 or 5 > 8;
E2: variable 1==ABC or variable 2>500  E1: "Yes" or "Ture";
E2: "Yes" or "True"
[Assumed that variable 1 is "ABD", variable 2 is "800".] 
==
(Equal)  Equal sign, indicating the same value.
Mostly it's used between functions.  iif(variable1==A, GOOD,BAD)  "GOOD"
[Assumed that variable1 is "A"] 
!=
(Not equal)  Not equal sign, indicating not have the indicated value.
Mostly it's used between functions.  iif(variable1!=A, GOOD,BAD)  "BAD"
[Assumed that variable1 is "A"] 
>
(Greater than or equal)  Used to compare expressions, indicating numeric values higher than the comparison.  iif(variable1 >100 , GOOD,BAD)  "BAD"
[Assumed that variable1 is "90"] 
>=
(Greater than)  Used to compare expressions, indicating numeric values the same or higher than the comparison. 


<
(Less than)  Used to compare expressions, indicating numeric values less than the comparison.  iif(variable1 <100 , Need improve,GOOD)  "Need improve"
[Assumed that variable1 is "90"] 
<=
(Less than or equal)  Used to compare expressions, indicating numeric values the same or less than the comparison.
