SimpleCalculatorKJ

Calculator node that evaluates a mathematical expression using inputs a and b.

Example

JSON Example

{
  "class_type": "SimpleCalculatorKJ",
  "inputs": {
    "expression": "a + b"
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
expression	STRING	required	-	"a + b"
a	*	optional	min: -10000000000, max: 10000000000, step: 0.01	0
b	*	optional	min: -10000000000, max: 10000000000, step: 0.01	0

Outputs

Index	Name	Type	Is List	Connection Reference
0	FLOAT	FLOAT	No	["{node_id}", 0]
1	INT	INT	No	["{node_id}", 1]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this SimpleCalculatorKJ node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• FLOAT (FLOAT): ["5", 0]
• INT (INT): ["5", 1]
