Atan(BigRational, Int32)
Returns the angle whose tangent is the specified number.
Declaration
public static BigRational Atan(BigRational x, int digits)Parameters
| Type | Name | Description |
|---|---|---|
| BigRational | x | A number representing a tangent. |
| System.Int32 | digits | The maximum number of fractional decimal digits in the return value.digits |
Returns
| Type | Description |
|---|---|
| BigRational | An angle, θ, measured in radians, such that -π/2 ≤ θ ≤ π/2. |
Remarks
Note: In the current version, the function has not yet been finally optimized for performance
and the accuracy of the last digits has not yet been ensured!
Atan(BigRational)
Computes the arc-tangent of a value.
