Range Integer (Mikey)

Documentation

• Class name: Range Integer
• Category: Mikey/Utils
• Output node: False

The RangeInteger node is designed to generate a list of integers within a specified range, using a step value derived from a seed. It then selects an integer from this list based on an offset calculated from the seed, providing a way to deterministically select a number within a range.

Input types

Required

• start
  • Specifies the starting point of the range. It is crucial for defining the lower bound of the generated list of numbers.
  • Comfy dtype: INT
  • Python dtype: int
• end
  • Defines the end point of the range, setting the upper limit for the list of integers to be generated.
  • Comfy dtype: INT
  • Python dtype: int
• step
  • Determines the interval between each number in the range. It is derived from the seed value, adding a layer of determinism to the selection process.
  • Comfy dtype: INT
  • Python dtype: int
• seed
  • Used as a basis for calculating the step value and the offset for selecting the final number. It introduces a deterministic element to the number selection.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• int
  • Comfy dtype: INT
  • The integer selected from the generated list based on the seed-derived offset.
  • Python dtype: int
• string
  • Comfy dtype: STRING
  • A string representation of the selected integer, providing a textual format of the output.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
