法律C# 中的 Single.ToString 方法
C# 中的 Single.ToString() 方法用于将该实例的数值转换为等效的字符串表示。
语法
语法如下 −
public override string ToString ();
示例
让我们来看一个示例 −
using System;
public class Demo {
public static void Main(){
float f1 = 10.0f/0.0f;
float f2 = -3.0f;
Console.WriteLine("Value1 (String representation) = "+f1.ToString());
Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
Console.WriteLine("Is Value1 a positive infinity? = "+Single.IsPositiveInfinity(f1));
Console.WriteLine("
Value1 (String representation) = "+f2.ToString());
Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
Console.WriteLine("Is Value2 a positive infinity? = "+Single.IsPositiveInfinity(f2));
}
}输出
这将生成以下输出 −
Value1 (String representation) = ∞ Hashcode for Value1 = 2139095040 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Is Value1 NaN? = False Is Value1 a positive infinity? = True Value1 (String representation) = -3 Hashcode for Value2 = -1069547520 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False Is Value2 NaN? = False Is Value2 a positive infinity? = False
示例
让我们再看一个示例 −
using System;
public class Demo {
public static void Main(){
float f1 = 5.0f/0.0f;
float f2 = 0.0f/0.0f;
Console.WriteLine("Value1 (String representation) = "+f1.ToString());
Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
Console.WriteLine("Is Value1 a negative infinity? = "+Single.IsNegativeInfinity(f1));
Console.WriteLine("
Value2 (String representation) = "+f2.ToString());
Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
Console.WriteLine("Is Value2 a negative infinity? = "+Single.IsNegativeInfinity(f2));
}
}输出
这将生成以下输出 −
Value1 (String representation) = ∞ Hashcode for Value1 = 2139095040 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Is Value1 NaN? = False Is Value1 a negative infinity? = False Value2 (String representation) = NaN Hashcode for Value2 = -4194304 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False Is Value2 NaN? = True Is Value2 a negative infinity? = False
