Difference
What It Does
The Difference node calculates the absolute difference between two numbers. It's useful for measuring the gap between values while disregarding which is larger.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| A | First number in the comparison | Number | No |
| B | Second number in the comparison | Number | No |
| Precision | How many decimal places to round to | Number | No |
Outputs
| Name | Description | Type |
|---|---|---|
| Difference | The absolute difference between A and B | Number |
How to Use It
- Drag the Difference node into your graph.
- Connect your first number to the "A" input (e.g.,
7.84) or use the default (0). - Connect your second number to the "B" (e.g.,
13) input or use the default (0). - Optionally set the "Precision" input (defaults to 2 decimal places).
- The output will be the absolute value of the difference between the two numbers (e.g.,
5.16)
Tips
- The result is always positive, regardless of which input is larger.
- Use the precision input to control rounding (e.g., 0 for integers, 2 for cents).
