Single.MinValueSingle.MinValueSingle.MinValueSingle.MinValue Field

Определение

Представляет минимально допустимое значение типа Single.Represents the smallest possible value of Single. Это поле является константой.This field is constant.

``public: float MinValue = -3.402823E+38;``
``public const float MinValue = -3.402823E+38;``
``val mutable MinValue : single``
``Public Const MinValue As Single  = -3.402823E+38``

Примеры

В следующем примере кода показана MinValue константа.The following code example demonstrates the MinValue constant.

``````if ( s < Single::MinValue )
{
Console::WriteLine( "Your number is smaller than a Single." );
}
``````
``````if (s < Single.MinValue)
{
Console.WriteLine("Your number is smaller than a Single.");
}
``````
``````If S < Single.MinValue Then
Console.WriteLine("Your number is smaller than a Single.")
End If
``````

Комментарии

Значение этой константы отрицательно 3.402823 E38.The value of this constant is negative 3.402823e38.

Результат операции меньше, чем Single.MinValue. Single.NegativeInfinityThe result of an operation that is less than Single.MinValue is Single.NegativeInfinity. В следующем примере результаты операций Single.NegativeInfinity вычитания и умножения выполняются, если результат Single.MinValueменьше.In the following example, Single.NegativeInfinity results from subtraction and multiplication operations when the result is less than Single.MinValue.

``````using System;

public class Example
{
public static void Main()
{
float result1 = -8.997e37f + -2.985e38f;
Console.WriteLine("{0} (Negative Infinity: {1})",
result1, Single.IsNegativeInfinity(result1));

float result2 = -1.5935e25f * 7.948e32f;
Console.WriteLine("{0} (Negative Infinity: {1})",
result2, Single.IsNegativeInfinity(result2));

// The example displays the following output:
//    -Infinity (Negative Infinity: True)
//    -Infinity (Negative Infinity: True)
