c语言isfinite用法,C# Single.IsFinite()用法及代码示例

Single.IsFinite()方法用于检查float值是否超出范围。

用法： public static bool IsFinite (float value);

返回值：如果值是有限的，则此方法返回true，否则返回false。

以下示例程序旨在说明Single.IsFinite()方法的使用：

示例1:

// C# program to demonstrate the

// Single.IsFinite() Method

using System;

using System.Globalization;

class GFG {

// Main Method

public static void Main()

{

// Declaring and initializing value1

float value1 = 1654.268416f;

// using IsFinite() method

bool value = Single.IsFinite(value1);

// Displaying the result

if (value)

Console.WriteLine("{0} is finite", value1);

else

Console.WriteLine("{0} is not finite", value1);

}

}

输出：

1654.268 is finite

示例2:

// C# program to demonstrate the

// Single.IsFinite() Method

using System;

using System.Globalization;

class GFG {

// Main Method

public static void Main()

{

// Declaring and initializing value1

float value1 = (float)Math.Pow(2, 10000000);

// using IsFinite() method

bool value = Single.IsFinite(value1);

// Displaying the result

if (value)

Console.WriteLine("{0} is finite", value1);

else

Console.WriteLine("{0} is not finite", value1);

}

}

输出：

Infinity is not finite
