Number Scaler

Documentation

• Class name: NumberScaler
• Category: Art Venture/Utils
• Output node: False

The NumberScaler node is designed to scale a numerical value within a specified range to a new range, effectively normalizing or denormalizing the value based on the provided minimum and maximum boundaries.

Input types

Required

• min
  • Specifies the minimum value of the original range. It sets the lower boundary for scaling the input value.
  • Comfy dtype: FLOAT
  • Python dtype: float
• max
  • Defines the maximum value of the original range. It sets the upper boundary for scaling the input value.
  • Comfy dtype: FLOAT
  • Python dtype: float
• scale_to_min
  • Determines the minimum value of the target scaling range. It influences the lower limit of the output scaled value.
  • Comfy dtype: FLOAT
  • Python dtype: float
• scale_to_max
  • Sets the maximum value of the target scaling range. It influences the upper limit of the output scaled value.
  • Comfy dtype: FLOAT
  • Python dtype: float
• value
  • The numerical value to be scaled from its original range to the target range.
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• float
  • Comfy dtype: FLOAT
  • The scaled numerical value, adjusted to fit within the new specified range.
  • Python dtype: float

Usage tips

• Infra type: CPU
• Common nodes: unknown
