Tip:
To better understand how Functions work, check out the Use Expressions page in the How To section.
To help you define particular Expressions or include individual operations while designing your app, an out of the box set of Functions is provided within the designer.
Note:
Depending on the function specifications some have a graphical representation, while others do not.
Start using the available functions by selecting the needed operator, input the parameters, and wait for the output value to be returned.
Note:
- The accepted parameters can be the same type of arguments or implicit cast of arguments.
- The output value can be primitive or an object.
Function Operators
Mathematical Operators and Functions
Please access this page for more details.
Arithmetic Operators
| Operator | Description | Example |
|---|---|---|
+ | Addition | x = y + 2 |
- | Subtraction | x = y - 2 |
* | Multiplication | x = y * 2 |
/ | Division | x = y / 2 |
% | Modulus (division remainder) | x = y % 2 |
++ | Increment | x = ++y |
-- | Decrement | x = --yx = y-- |
String Operators
We'll use the following hypothesis to present the string operators: text1 = "Good ", text2 = "Morning", and text3 = "".
| Operator | Example | text1 | text2 | text3 |
|---|---|---|---|---|
+= | text1 += text2 | "Good Morning" | "Morning" | "" |
& | text3 = text1 + text2 | "Good " | "Morning" | "Good Morning" |
Comparison Operators
We'll use the following hypothesis to present the comparison operators: x = 5.
| Operator | Description | Comparing | Returns |
|---|---|---|---|
=, == | equal to ("=" is the same as "==") | x == 8x == 5 | false true |
> | greater than | x > 8 | false |
>= | greater than or equal to | x >= 8 | false |
!= | not equal | x != 8 | true |
< | less than | x < 8 | true |
<= | less than or equal to | x <= 8 | true |
Logical Operators
We'll use the following hypothesis to present the logical operators: x=6 and y=3.
| Operator | Function | Description | Example |
|---|---|---|---|
!, not, NOT | Not() | not | !(x === y) is true |
&&, and, AND | And() | and | (x < 10 && y > 1) is true |
||, or, OR | Or() | or | (x === 5 || y === 5) is false |
Other Operators
The in operator returns a true result if the specified property is in the specified object, otherwise, it returns a false result.
Note:
The
inoperator only supports primitive data types, such asstring,number,boolean,null.
Theinoperator is not supported in Data Service scenarios usingchoice-set. You can use thecontainsoperator instead, but only for one input.
