07.4 Functions

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.

tip

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

  • Result of the expression: Value.
  • Example: If 3.ValueSV = 'A', then 1. If 3.ValueSV = 'Abc1000', then 2.

replace​

This operator replaces selected values in a string or number with specified values.

  • Result of the expression: Text or number with character replacement.
  • Example: If 3.ValueSV = 'Hi Latenode', then 'Test Latenode'.

trim​

This operator removes spaces at the beginning and end of a string.

  • Result of the expression: Text without spaces.
  • Example: If 3.ValueSV = ' Hi Latenode ', then 'Hi Latenode'.

substring​

This operator outputs a portion of a string or number from a selected starting position not inclusive to a chosen ending position, inclusive.

  • Result of the expression: A portion of text.
  • Example: If 3.ValueSV = 'Latenode', then 'a'.

indexOf​

This operator provides the position of the first occurrence of a search value in a string or number.

tip

This operator returns "-1" if the search value is not found.

  • Result of the expression: A portion of text.
  • Example: If 3.ValueSV = 'Latenode', then 4.
