Inputs
| Title | Data Type | Description | Default Value | Notes |
|---|---|---|---|---|
| A | number | The first operand for the operation. | (Required) | The input will be coerced into a number if it is not a number. |
| B | number | The second operand for the operation. | (Required for binary operators) | The input will be coerced into a number if it is not a number. |
Outputs
| Title | Data Type | Description | Notes |
|---|---|---|---|
| Output | number | The result of the operation. |

| Operation | The operation to perform on the input values. Options include +, -, *, /, ^, %, abs, and negate. | + | Yes | string |
Example 1: Performing a simple addition
- Create an Evaluate Node and set the
Operationto+. - Create two Number nodes, set their values to
2and3respectively. - Connect the Number nodes to the
AandBinputs of the Evaluate Node. - Run the graph. The output of the Evaluate Node should be
5.
Error Handling
If the operation fails (for example, if you try to divide by zero), the Evaluate node will error.
FAQ
Q: What if I want to perform a different operation based on the input?
A: You can use the Operation input port to dynamically change the operation based on the input. The input will be coerced into a string and must match one of the supported operations.
