NumberUnaryOperation

Documentation

  • Class name: CM_NumberUnaryOperation
  • Category: math/number
  • Output node: False

This node performs unary operations on numbers, allowing for the manipulation of a single numerical input through predefined operations.

Input types

Required

  • op
    • Specifies the unary operation to be performed on the input number. The choice of operation affects the outcome of the node's computation.
    • Comfy dtype: COMBO[STRING]
    • Python dtype: str
  • a
    • The numerical input on which the unary operation will be performed. This input is central to the node's functionality.
    • Comfy dtype: NUMBER
    • Python dtype: number

Output types

  • number
    • Comfy dtype: NUMBER
    • The result of applying the specified unary operation on the input number.
    • Python dtype: float

Usage tips

  • Infra type: CPU
  • Common nodes: unknown
