ComfyUI Node: String to Int

String to Int:

The String to Int node is designed to convert a string representation of a number into an integer. This node is particularly useful when you have numeric data stored as strings and need to perform arithmetic operations or other integer-specific tasks. It automatically strips any whitespace from the input string before attempting the conversion, ensuring that formatting issues do not interfere with the process. If the string cannot be successfully parsed into an integer, the node provides a fallback mechanism by returning a default integer value specified by the user. This feature ensures robustness and flexibility, allowing you to handle unexpected or malformed input gracefully.

String to Int Input Parameters:

string

This parameter represents the string input that you want to convert into an integer. The node will strip any leading or trailing whitespace from this string before attempting the conversion. This ensures that minor formatting issues do not prevent successful parsing. There is no explicit minimum or maximum value for this parameter, as it is a string, but it should ideally represent a valid integer to avoid fallback to the default value.

default

The default parameter specifies the integer value to return if the string cannot be parsed into an integer. This provides a safety net for cases where the input string is not a valid representation of an integer. The default value is set to 0, but you can specify any integer that suits your needs. This parameter ensures that the node can handle unexpected input gracefully without causing errors in your workflow.

String to Int Output Parameters:

INT

The output of this node is an integer, which is the result of converting the input string. If the conversion is successful, the output will be the integer representation of the string. If the conversion fails, the output will be the default integer value specified by the user. This output is crucial for workflows that require numeric data in integer form, enabling further processing or calculations.

String to Int Usage Tips:

• Ensure that the input string is a valid representation of an integer to avoid falling back to the default value. This can be done by pre-validating the string format if possible.
• Use the default parameter to specify a meaningful fallback value that makes sense in the context of your workflow, ensuring that the node's output remains useful even when the input is not ideal.

String to Int Common Errors and Solutions:

Invalid string format

• Explanation: The input string does not represent a valid integer, causing the node to return the default value.
• Solution: Verify that the input string is correctly formatted as an integer. Remove any non-numeric characters and ensure there are no leading or trailing spaces.

Unexpected default value

• Explanation: The node returns the default value because the input string could not be parsed as an integer.
• Solution: Check the default parameter to ensure it is set to a value that is appropriate for your workflow. Adjust the default value if necessary to better handle cases where the input string is invalid.
