Parse Number
What It Does
The Parse Number node converts a string representation of a number into an actual number value. If the conversion fails (resulting in NaN), the node throws an error.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| Value | The string to convert to a number | String | Yes |
Outputs
| Name | Description | Type |
|---|---|---|
| Value | The converted number value | Number |
How to Use It
- Drag the Parse Number node into your graph.
- Connect a string value to the "Value" input.
- The node attempts to convert the string to a number.
- If successful, the number is output.
- 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.
