C# Single.IsPositiveInfinity()用法及代码示例

// C# program to illustrate the 
// Single.IsPositiveInfinity(Single) 
// Method 
using System; 
  
class GFG { 
  
    // Main method 
    static public void Main() 
    { 
  
        // Dividing a Positive number by zero 
        // results in positive infinity. 
  
        // Dividing a number directly by 0 
        // produces an error 
        // So 0 is stored in a variable first 
  
        float zero = 0.0f; 
        float value = 10.0f; 
        float result = value / zero; 
  
        // Printing result 
        Console.WriteLine(result); 
  
        // Check result using IsPositiveInfinity() Method 
        Console.WriteLine(Single.IsPositiveInfinity(result)); 
  
        // Floating point operation that exceeds 
        // Single.MaxValue is Positive Infinity 
        result = (1.402823E+38f + ((float)9.985e307)); 
  
        // Printing result 
        Console.WriteLine(result); 
  
        // Check result using IsPositiveInfinity() Method 
        Console.WriteLine(Single.IsPositiveInfinity(result)); 
    }
