Random Number

Documentation

• Class name: Random Number
• Category: WAS Suite/Number
• Output node: False

This node generates random numbers based on specified parameters, including the type of number (integer, float, or boolean), and the range within which the number should fall. It allows for the generation of random numbers with a seed to ensure reproducibility.

Input types

Required

• number_type
  • Specifies the type of number to generate, which can be an integer, float, or boolean. This affects the method used for generating the random number.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• minimum
  • The minimum value in the range from which the random number will be generated.
  • Comfy dtype: FLOAT
  • Python dtype: float
• maximum
  • The maximum value in the range from which the random number will be generated.
  • Comfy dtype: FLOAT
  • Python dtype: float
• seed
  • A seed value to ensure the reproducibility of the random number generation.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• number
  • Comfy dtype: NUMBER
  • The generated random number.
  • Python dtype: Union[int, float, bool]
• float
  • Comfy dtype: FLOAT
  • The generated random number represented as a float.
  • Python dtype: float
• int
  • Comfy dtype: INT
  • The generated random number rounded to the nearest integer.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
