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
