MathN.Atan2<TNumeric> Method

Returns the angle whose tangent is the quotient of two specified numbers.

Definition

Namespace: Jodosoft.Numerics
Assembly: Jodosoft.Numerics (in Jodosoft.Numerics.dll) Version: 2.0
public static TNumeric Atan2<TNumeric>(
	TNumeric x,
	TNumeric y
)
where TNumeric : struct, new(), INumeric<TNumeric>

Parameters

x  TNumeric
The x coordinate of a point.
y  TNumeric
The y coordinate of a point.

Type Parameters

TNumeric

Return Value

TNumeric
An angle, θ, measured in radians, such that tan(θ) = y / x, where (x, y) is a point in the Cartesian plane. Observe the following:
  • For (x, y) in quadrant 1, 0 < θ < π/2.
  • For (x, y) in quadrant 2, π/2 < θ ≤ π.
  • For (x, y) in quadrant 3, -π ≤ θ < -π/2.
  • For (x, y) in quadrant 4, -π/2 < θ < 0.
For points on the boundaries of the quadrants, the return value is the following:
  • If y is 0 and x is not negative, θ = 0.
  • If y is 0 and x is negative, θ = π.
  • If y is positive and x is 0, θ = π/2.
  • If y is negative and x is 0, θ = -π/2.
  • If y is 0 and x is 0, θ = 0.

Remarks

This method may return NaN or Infinity. If NaN or Infinity cannot be represented by TNumeric, then this method may throw an ArithmeticException.
