Square Root
What It Does
The Square Root node calculates the square root of a number - the value which, when multiplied by itself, equals the original number. It's essential for geometric calculations and creating non-linear scaling.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| Radicand | The number to find the square root of | Number | Yes |
Outputs
| Name | Description | Type |
|---|---|---|
| Value | The square root of the input number | Number |
How to Use It
- Drag the Square Root node into your graph.
- Connect a positive number to the "Radicand" input.
- The output will be the square root of the input.
- Use this for creating non-linear scales or calculating geometric properties.
Tips
- The input should be zero or positive for real number results.
- Using a negative input will result in NaN (Not a Number).
- Square root grows slower than linear functions, useful for compression effects.
See Also
- Pow: For calculating powers, including the reverse operation of square root.
- Abs: For ensuring a value is positive before taking its square root.
Use Cases
- Non-linear Scaling: Create spacing or sizing scales that grow more gradually.
- Distance Calculations: Compute distances in 2D or 3D space.
- Visual Dampening: Reduce extreme values while preserving smaller ones.
