Public Shared Function Atanh (d As Double) As Double
Parameters
- d
- Double
A number representing a hyperbolic tangent, where d
must be greater than or equal to -1, but less than or equal to 1.
Returns
An angle, θ, measured in radians, such that -∞ < θ < -1, or 1 < θ < ∞.
-or-
NaN if d
< -1 or d
> 1 or d
equals NaN.
Remarks
Multiply the return value by 180/Math.PI to convert from radians to degrees.
