Scala Float compare()用法及代碼示例


如果第一個數字等於第二個數字,則使用compare()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).compare(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 compare() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Applying compare method 
        val result = (5).compare(5) 
          
        // Displays output 
        println(result) 
      
    } 
} 
輸出:
0

範例2:

// Scala program of Float compare() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Applying compare method 
        val result = (5).compare(2) 
          
        // Displays output 
        println(result) 
      
    } 
} 
輸出:
1

範例3:

// Scala program of Float compare() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Applying compare method 
        val result = (5).compare(9) 
          
        // Displays output 
        println(result) 
      
    } 
} 
輸出:
-1
