C#의 Single.ToString() 메서드는 이 인스턴스의 숫자 값을 해당하는 문자열 표현으로 변환하는 데 사용됩니다.
구문
구문은 다음과 같습니다 -
public override string ToString ();
예
이제 예를 살펴보겠습니다 -
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("\nValue1 (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));
}
} 출력
이것은 다음과 같은 출력을 생성합니다 -
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
예
이제 다른 예를 살펴보겠습니다 -
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("\nValue2 (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));
}
} 출력
이것은 다음과 같은 출력을 생성합니다 -
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
