About Functions

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.

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`
