Double.Log 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

重载

Log(Double, Double)	计算指定基数中某个值的对数。
Log(Double)	计算值的自然 (base-E 对数。

Log(Double, Double)

Source:

Double.cs

计算指定基数中某个值的对数。

public:
 static double Log(double x, double newBase) = System::Numerics::ILogarithmicFunctions<double>::Log;

public static double Log (double x, double newBase);

static member Log : double * double -> double

Public Shared Function Log (x As Double, newBase As Double) As Double

参数

x

Double

要计算其对数的值。

newBase

Double

计算对数的基数。

返回

Double

的基newBase 数对数 x。

实现

Log(TSelf, TSelf)

Log(Double)

Source:

Double.cs

计算值的自然 (base-E 对数。

public:
 static double Log(double x) = System::Numerics::ILogarithmicFunctions<double>::Log;

public static double Log (double x);

static member Log : double -> double

Public Shared Function Log (x As Double) As Double

参数

x

Double

要计算其自然对数的值。

返回

Double

x 的自然对数。

实现
