单身。C# 中的 IsNegative()方法,示例

原文:https://www . geesforgeks . org/single-is negative-method in-c-sharp-with-examples/

单身。IsNegative(Single)方法用于返回一个值,该值指示指定的数字是否为负数。

语法:公共静态 bool 为 negative(float f);

返回值:如果 f 的计算结果为负,则该方法返回,否则返回假。

以下程序说明了 Single 的使用。IsNegative() 方法:

例 1:

// C# program to demonstrate the
// Single.IsNegative() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        float value1 = 1011.5615f;

        // using IsNegative() method
        bool value = Single.IsNegative(value1);

        // Displaying the result
        if (value)
            Console.WriteLine("{0} is Negative", value1);
        else
            Console.WriteLine("{0} is not Negative", value1);
    }
}

Output:

1011.562 is not Negative

例 2:

// C# program to demonstrate the
// Single.IsNegative() Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        float value1 = -10.651f;

        // using IsNegative() method
        bool value = Single.IsNegative(value1);

        // Displaying the result
        if (value)
            Console.WriteLine("{0} is Negative", value1);
        else
            Console.WriteLine("{0} is not Negative", value1);
    }
}

Output:

-10.651 is Negative
