How to Use It

  1. Drag the Parse Number node into your graph.

  2. Connect a string value to the "Value" input.

  3. The node attempts to convert the string to a number.

  4. If successful, the number is output.

  5. If the string cannot be parsed as a number, an error is thrown.

Tips

  • This node is stricter than JavaScript's built-in parsing as it throws an error on invalid input.

  • Use this node when you need to ensure numerical operations will work correctly.

  • Consider using a Try/Catch node to handle potential parsing errors gracefully.
