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 = --y

x = 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 == 8

x == 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 in operator only supports primitive data types, such as string, number, boolean, null.
The in operator is not supported in Data Service scenarios using choice-set. You can use the contains operator instead, but only for one input.
