ComfyUI Node: Range Float (Mikey)

Range Float (Mikey):

The Range Float node is designed to generate a sequence of floating-point numbers within a specified range and select a specific number from that sequence based on an offset value derived from a seed. This node is particularly useful for creating a list of numbers with a defined start, end, and step value, and then retrieving a specific number from that list. The primary benefit of this node is its ability to produce a predictable and reproducible number from a range, which can be useful in various AI art applications where consistent results are desired.

Range Float (Mikey) Input Parameters:

start

The start parameter defines the beginning value of the range of floating-point numbers. It determines where the sequence will start. The minimum value for this parameter is 0, and the maximum value is 0xffffffffffffffff. The default value is set to 0. This parameter is crucial as it sets the lower boundary of the range.

end

The end parameter specifies the ending value of the range of floating-point numbers. It determines where the sequence will stop. Similar to the start parameter, the minimum value is 0, and the maximum value is 0xffffffffffffffff. The default value is also set to 0. This parameter is essential as it sets the upper boundary of the range.

step

The step parameter defines the increment between each number in the range. It determines the spacing between the numbers in the sequence. The minimum value for this parameter is 0, and the maximum value is 0xffffffffffffffff. The default value is set to 0. This parameter is important as it controls the granularity of the sequence.

seed

The seed parameter is an integer that is used to calculate the offset within the generated list of numbers. The minimum value for this parameter is 0, and the maximum value is 0xffffffffffffffff. The default value is set to 0. This parameter is significant as it ensures the reproducibility of the selected number from the range.

Range Float (Mikey) Output Parameters:

FLOAT

The FLOAT output parameter returns the floating-point number selected from the generated range based on the offset calculated using the seed. This output is crucial as it provides the specific number from the sequence that can be used in further computations or artistic processes.

STRING

The STRING output parameter returns the selected floating-point number in string format. This output is useful for displaying the number in a textual context or for logging purposes.

Range Float (Mikey) Usage Tips:

• Ensure that the start, end, and step parameters are set correctly to generate the desired range of numbers. For example, if you want a range from 1.0 to 10.0 with a step of 0.5, set start to 1.0, end to 10.0, and step to 0.5. - Use the seed parameter to control the reproducibility of the selected number. By using the same seed value, you can ensure that the same number is selected from the range each time.

Range Float (Mikey) Common Errors and Solutions:

"division by zero"

• Explanation: This error occurs if the step parameter is set to 0, which results in an attempt to divide by zero when generating the range.
• Solution: Ensure that the step parameter is set to a non-zero value to avoid this error.

"index out of range"

• Explanation: This error occurs if the seed value is larger than the length of the generated list of numbers, causing an invalid index access.
• Solution: Ensure that the seed value is within the range of the generated list's length. Adjust the start, end, and step parameters to generate a sufficiently large list or reduce the seed value.
