Tangent

Documentation

• Class name: DF_Tangent
• Category: Derfuu_Nodes/Math/Trigonometry
• Output node: False

The DF_Tangent node calculates the tangent or arctangent of a given value, with the option to specify the angle measurement unit (degrees or radians). This functionality allows for the transformation and analysis of angular data within mathematical and trigonometric computations.

Input types

Required

• value
  • The numerical value for which the tangent or arctangent is to be calculated. This input is crucial for determining the specific angle or its tangent value.
  • Comfy dtype: FLOAT
  • Python dtype: float
• type_
  • Specifies the angle measurement unit for the input value, either as radians (RAD) or degrees (DEG), affecting how the value is interpreted and processed.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• arcTan
  • A boolean flag that determines whether to calculate the arctangent (True) or tangent (False) of the input value, allowing for flexibility in trigonometric calculations.
  • Comfy dtype: COMBO[BOOLEAN]
  • Python dtype: bool

Output types

• float
  • Comfy dtype: FLOAT
  • The calculated tangent or arctangent of the input value, provided as a floating-point number.
  • Python dtype: float

Usage tips

• Infra type: CPU
• Common nodes: unknown
