Algorithm

Operators in this group ensure the execution of logical operations with operands and output the result. The outcome of these operations varies.

Result

If

t outputs a specified value when conditions are met or a different value if the conditions are not met.

Result of the expression: Specified value.

Example: If 3.ValueSV = 10, then true. If 3.ValueSV = 11, then false.

()

This operator provides logical and mathematical isolation for any expressions.

Result of the expression: -.

not

This operator provides logical negation of specified/received boolean values.

Result of the expression: Negation of the value.

Example: If 3.ValueSV is TRUE, then FALSE

if empty

It outputs a specified value if the operand is absent (null), and the value of the operand if it is present.

Result of the expression: The value.

Example: If 3.ValueSV is absent (null), then 5. If 3.ValueSV = 50, then 50.

empty

This operator checks for the absence of values in the operand.

Result of the expression: TRUE/FALSE.

Example: If 3.ValueSV is absent (null), then TRUE. If 3.ValueSV = "May", then FALSE.

contains

This operator checks for the presence of selected characters in a string, number, or array (including an array of boolean values), regardless of their location.

Result of the expression: TRUE/FALSE.

Example: If 3.ValueSV = "Hello Latenode", then TRUE. If 3.ValueSV = "Hi Latenode", then FALSE.

starts with

This operator checks for the presence of selected characters at the beginning of a string or number.

Result of the expression: TRUE/FALSE.

Example: If 3.ValueSV = "June", then TRUE. If 3.ValueSV = "May", then FALSE. If 3.ValueSV = "1000", then FALSE.

ends with

This operator checks for the presence of selected characters at the end of a string or number.

Result of the expression: TRUE/FALSE.

Example: If 3.ValueSV = "June", then TRUE. If 3.ValueSV = "May", then FALSE. If 3.ValueSV = "1000", then FALSE.

matches pattern

This operator checks for a match between the operand and a regular expression.

Result of the expression: TRUE/FALSE.

Example: If 3.ValueSV = "Abc", then TRUE. If 3.ValueSV = 2000, then FALSE.

to lower

This operator converts a string to lowercase.

Result of the expression: Lowercase text.

Example: If 3.ValueSV = 'TEST', then test.

to upper

This operator converts a string to uppercase.

Result of the expression: Uppercase text.

Example: If 3.ValueSV = 'test', then TEST.

length

This operator outputs the number of characters in a string or the number of values in an array.

Result of the expression: A number.

Example: If 3.ValueSV = 'test', then 4.

get

This operator outputs a JSON parameter or an array element.

Result of the expression: Parameter.

Example: The value of the parameter ValueWH1 from the provided JSON. For example, if ValueWH1 = 15, then 15.

Example: The value of the element in the provided array ValueWH with index 1. For instance, if ValueWH1 = 15, then 15.

switch

This operator checks if the expression matches the selected operand and outputs a value when a match is found. The operand can be a boolean value, a string, or a number.

💡

The function operator the result corresponding to the first matching value.
