Compare Block Screenshot

​
Overview

The Compare Block allows you to perform comparison operations between two input values. It supports various comparison functions including equality, inequality, less than, greater than, and logical operations such as AND, OR, XOR, NAND, NOR, and XNOR.

​
Inputs

​
A
any
The first value for comparison. Required.
​
B
any
The second value for comparison. Required.
​
Comparison Function
string
The comparison function to use. Only available when “Use Comparison Function Input” is enabled in settings.

​
Outputs

​
Output
boolean
The result of the comparison operation.

​
Editor Settings

​
Comparison Function
string
default:"=="
The comparison function to be used for the operation. Available options are:
  • ==: Equal to
  • !=: Not equal to
  • <: Less than
  • >: Greater than
  • <=: Less than or equal to
  • >=: Greater than or equal to
  • and: Logical AND
  • or: Logical OR
  • xor: Logical XOR
  • nand: Logical NAND
  • nor: Logical NOR
  • xnor: Logical XNOR
​
Use Comparison Function Input
boolean
default:false
When enabled, adds a “Comparison Function” input port that can override the comparison function setting.

​
Example: Compare two numbers

  1. Create a Compare Block and set the Comparison Function to >.
  2. Create two Number Blocks, one with the value 5 and the other with the value 3.
  3. Connect the Number Blocks to the A and B inputs of the Compare Block respectively.
  4. Run the flow. The output of the Compare Block will be true, because 5 is greater than 3.

​
Error Handling

If input A is not provided:
  • For == comparison: Returns true if B is also not provided, false otherwise
  • For != comparison: Returns true if B is provided, false otherwise
  • For all other comparisons: Returns false
If the inputs are not of the same type, the block will attempt to coerce the second input (B) to the type of the first input (A).

​
FAQ

If the inputs are not of the same type, the block will attempt to coerce the second input (B) to the type of the first input (A). If the coercion is not possible, the comparison will be performed with the original values.
Yes, you can use the Compare Block to compare arrays or objects. The comparison will be performed using a deep equality check that compares all nested values.
