Scala Float compareTo()用法及代碼示例

如果第一個數字等於第二個數字，則使用compareTo()方法返回0；如果第一個數字大於第二個數字，則返回1；如果第一個數字小於第二個數字，則返回-1。

函數定義: (First_Number).compareTo(Second_Number)

返回類型: It returns 0 if the first number is equal to the second number, 1 if the first number is greater then the second number and finally -1 if the first number is less than the second number.

範例1：

// Scala program of Float compareTo() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating first float number  
        val m1 = 3.4
          
        // Applying compareTo method 
        val result = m1.compareTo(3.4) 
          
        // Displays output 
        println(result) 
      
    } 
}

輸出：

範例2：

// Scala program of Float compareTo() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating first float number  
        val m1 = 3.4
          
        // Applying compareTo method 
        val result = m1.compareTo(2.4) 
          
        // Displays output 
        println(result) 
      
    } 
}

輸出：

範例3：

// Scala program of Float compareTo() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating first float number  
        val m1 = 3.4
          
        // Applying compareTo method 
        val result = m1.compareTo(9.5) 
          
        // Displays output 
        println(result) 
      
    } 
}

輸出：

-1
