🔧 CR String To Number

Documentation

• Class name: CR String To Number
• Category: 🧩 Comfyroll Studio/🛠️ Utils/🔧 Conversion
• Output node: False

This node is designed to convert a string representation of a number into its numerical form, offering options for rounding the result to the nearest integer, rounding up, or rounding down. It abstracts the complexity of handling numeric conversions and rounding decisions from the user, providing a straightforward interface for processing textual numeric data.

Input types

Required

• text
  • The text input is the string representation of a number that the node attempts to convert into a numerical form. Its correctness is crucial for the successful execution of the node.
  • Comfy dtype: STRING
  • Python dtype: str
• round_integer
  • This parameter determines the rounding strategy (nearest, up, or down) to be applied to the converted number, affecting the final integer output.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str

Output types

• INT
  • Comfy dtype: INT
  • The integer output of the conversion process, affected by the chosen rounding strategy.
  • Python dtype: int
• FLOAT
  • Comfy dtype: FLOAT
  • The floating-point representation of the input text, providing a non-rounded numerical version.
  • Python dtype: float
• show_help
  • Comfy dtype: STRING
  • A URL to the node's documentation, offering additional help and examples.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
