Scala Float compareTo()用法及代码示例


如果第一个数字等于第二个数字,则使用compareTo()方法返回0;如果第一个数字大于第二个数字,则返回1;如果第一个数字小于第二个数字,则返回-1。

函数定义: (First_Number).compareTo(Second_Number)

返回类型: 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.



范例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) 
      
    } 
} 
输出:
0

范例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) 
      
    } 
} 
输出:
1

范例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) 
      
    } 
} 
输出:
-1
