# Documentation

- Class name: Compare
|

- Category: Logic
|
|
- Output node: False

Compare节点旨在根据指定的比较操作（如相等、不等、大于、小于）评估两个输入之间的关系。它将比较逻辑抽象成一个简单的接口，使用户能够动态评估和处理其数据或变量的条件。
|
|
|
|
# Input types
|
|
## Required
|
|
- a
|
|
- 第一个待比较的输入。它在决定比较操作结果中起着至关重要的作用。
|
|
- Comfy dtype: *
|
|
- Python dtype: Any
|
|
- b
|
|
- 与第一个输入进行比较的第二个输入。它的值在评估指定比较条件时至关重要。
|
|
- Comfy dtype: *
|
|
- Python dtype: Any
|
|
- comparison
|
|
- 指定在两个输入之间执行的比较类型（如'=='、'!='、'<'、'>'、'<='、'>='）。这决定了用于比较的逻辑，直接影响结果。
|
|
- Comfy dtype: COMBO[STRING]
|
|
- Python dtype: str
|
|
|
|
# Output types
|
|
- B
|
|
- 比较操作的结果，表示两个输入之间的指定条件是否成立。
|
|
- Comfy dtype: BOOLEAN
|
|
- Python dtype: bool
|
|
|
|
|
|
## Usage tips
|
|
- Infra type: `CPU`
|
|
- Common nodes: unknown
