ROUND

The ROUND node in Magick rounds a floating-point number to the nearest integer value. It’s useful when you need to convert a float to an integer while minimizing rounding errors.

​
Inputs

  1. a (float, default: 0): The floating-point number to be rounded.

​
Outputs

  1. result (float): The rounded integer value.

​
Configuration

This node has no configuration options.

​
Usage

To use the ROUND node:

  1. Connect a node that outputs a floating-point number to the a input of the ROUND node.
  2. The rounded integer value will be available at the result output.
  3. Connect the result output to the input of another node as needed.

​
Example

Suppose you have a spell that calculates the average of two numbers, but you need the result as an integer. You can use the ROUND node to achieve this:

  1. Connect two NUMBER nodes to the inputs of an ADD node.
  2. Connect the output of the ADD node to the input of a DIVIDE node.
  3. Set the second input of the DIVIDE node to 2 using another NUMBER node.
  4. Connect the output of the DIVIDE node to the a input of a ROUND node.
  5. The rounded integer average will be available at the result output of the ROUND node.

Best Practices

  • Use the ROUND node when you need to convert a floating-point number to an integer while minimizing rounding errors.
  • Be aware that rounding can introduce small inaccuracies, especially when dealing with large numbers or numbers with many decimal places.

​
Common Issues

  • Make sure the input to the ROUND node is a floating-point number. Connecting a non-float input may result in unexpected behavior or errors.
  • Keep in mind that rounding can change the value of the number slightly. If you need to preserve the exact value, consider using a FLOOR or CEIL node instead.
