Range Float (Mikey)

Documentation

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

The Range Float node generates a list of floating-point numbers within a specified range using a step value, then selects a specific number based on a seed value. This node is useful for creating sequences of numbers with precision and selecting an element from the sequence in a deterministic manner.

Input types

Required

• start
  • Defines the starting point of the range. It is crucial for determining the lower bound of the generated sequence.
  • Comfy dtype: FLOAT
  • Python dtype: float
• end
  • Specifies the ending point of the range. It sets the upper limit for the sequence of numbers to be generated.
  • Comfy dtype: FLOAT
  • Python dtype: float
• step
  • Determines the increment between each number in the range. This value affects the density and total count of numbers in the sequence.
  • Comfy dtype: FLOAT
  • Python dtype: float
• seed
  • Used as a basis for selecting a specific number from the generated list. It ensures a deterministic selection process.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• float
  • Comfy dtype: FLOAT
  • The floating-point number selected from the generated sequence.
  • Python dtype: float
• string
  • Comfy dtype: STRING
  • The string representation of the selected floating-point number.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
