请编写函数fun(),它的功能是计算:s=(1-In(1)-In(2)-In(3)-…-1n(m))2s作为函数值返回。在C语言中可调用log(n)函数求In(n)。log函数的引用说明是double log(double x)。例如,若m的值为15,则fun()函数值为723.570801。注意:部分源程序给出如下。请勿改动主函数main和其他函数

C是一种通用的编程语言,常用于系统软件开发和嵌入式系统领域。数字在C语言中可以使用int和double两种类型定义。 int: int是整数类型,用于表示整数值。在C语言中,int类型的变量占用固定字节数,可以是有符号的或无符号的。有符号的int类型可以表示负数和正数,无符号的int类型只能表示非负数。

The ToString() method formats a Double value in the default ("G", or general) format of the current culture. If you want to specify a different format, precision, or culture, use the other overloads of the ToString method, as follows: Expand table To use formatFor cultureUse the over...
By default, numbers in MATLAB are of the data type double. You can use the class function to verify a variable's type. Get x = 100; xtype = class(x) xtype = 'double' Use the double function to convert variables that are not double precision to type double. Get y = true...
The following example converts each element in an array of UInt32 values to a Double value. C# Copy Run uint[] numbers = { UInt32.MinValue, 121, 12345, UInt32.MaxValue }; double result; foreach (uint number in numbers) { result = Convert.ToDouble(number); Console.WriteLine("Convert...
