ComfyUI Node: Range(Step) - Float

Range(Step) - Float:

The Range(Step)

• Float node is designed to generate a sequence of floating-point numbers based on specified start, stop, and step values. This node is particularly useful for creating smooth transitions or gradients in your AI art projects, where precise control over numerical ranges is required. By allowing you to define the start and stop points along with the step size, this node provides flexibility in generating a series of numbers that can be used for various creative purposes, such as adjusting parameters incrementally or creating dynamic effects. The node ensures high precision by utilizing decimal arithmetic, making it suitable for applications where accuracy is crucial.

Range(Step) - Float Input Parameters:

start

The start parameter specifies the initial value of the range. It determines where the sequence of numbers will begin. This parameter accepts floating-point numbers, with a default value of 0. The minimum and maximum values are -4096 and 4096, respectively. Adjusting the start value allows you to shift the entire range to begin at a different point, which can be useful for aligning the sequence with specific requirements in your project.

stop

The stop parameter defines the endpoint of the range. It indicates the value at which the sequence will terminate. Like the start parameter, it accepts floating-point numbers, with a default value of 0, and has a range from -4096 to 4096. The stop value is crucial for determining the length and coverage of the range, allowing you to control how far the sequence extends.

step

The step parameter determines the increment between each number in the sequence. It is a floating-point number that specifies how much each subsequent number in the range will increase or decrease from the previous one. The default value is 0, with a range from -4096 to 4096. By adjusting the step size, you can control the granularity of the sequence, making it finer or coarser depending on your needs.

end_mode

The end_mode parameter specifies whether the stop value is included in the range. It offers two options: "Inclusive" and "Exclusive," with "Inclusive" as the default. This parameter allows you to decide if the sequence should include the stop value as the last element, providing flexibility in how the range is constructed and used.

Range(Step) - Float Output Parameters:

range

The range output is a list of floating-point numbers generated based on the specified start, stop, and step values. This sequence represents the main output of the node, providing a series of numbers that can be used for various purposes in your project. The range is constructed with high precision, ensuring that the values are accurate and suitable for detailed applications.

range_sizes

The range_sizes output is a list of integers that indicates the number of elements in each generated range. This output provides insight into the size of each sequence, allowing you to understand the extent of the range and how many values it contains. It is useful for verifying that the range meets your expectations and for debugging purposes.

Range(Step) - Float Usage Tips:

• To create a smooth gradient effect, use small step values to generate a finely detailed range of numbers.
• When working with large ranges, ensure that the step size is appropriately set to avoid generating excessively large sequences that may impact performance.
• Use the "Inclusive" end mode if you need the stop value to be part of the range, which can be useful for ensuring that the sequence covers the entire desired interval.

Range(Step) - Float Common Errors and Solutions:

Uneven steps detected for start=<value>, stop=<value>, num_steps=<value>.

• Explanation: This error occurs when the calculated step size is not an integer, and the allow_uneven_steps parameter is set to "False."
• Solution: Adjust the start, stop, or num_steps values to ensure that the step size is an integer, or set allow_uneven_steps to "True" if uneven steps are acceptable.

List input for allow_uneven_steps is not supported.

• Explanation: This error is raised when multiple values are provided for the allow_uneven_steps parameter, which only supports a single value.
• Solution: Ensure that the allow_uneven_steps parameter is set to a single value, either "True" or "False."
