MathF.Asinh(Single) 方法

定义

返回双曲正弦值为指定数字的角度。Returns the angle whose hyperbolic sine is the specified number.

public:
 static float Asinh(float x);
public static float Asinh (float x);
static member Asinh : single -> single
Public Shared Function Asinh (x As Single) As Single

参数

x
Single

一个表示双曲正弦值的数字,其中 x 必须大于等于 NegativeInfinity 但小于等于 PositiveInfinityA number representing a hyperbolic sine, where x must be greater than or equal to NegativeInfinity, but less than or equal to PositiveInfinity.

返回

角度 θ,以弧度为单位,满足 -∞ < θ ≤ -1 或 1 ≤ θ < ∞。An angle, θ, measured in radians, such that -∞ < θ ≤ -1, or 1 ≤ θ < ∞.

-or- 如果 x 等于 NaN,则为 NaNNaN if x equals NaN.

注解

将返回值乘以 180/MathF.PI , 以将弧度转换为度。Multiply the return value by 180/MathF.PI to convert from radians to degrees.
