Scala Double <=(x: Long) 方法

Scala Double <=(x: Long) 方法

在 Scala 中，Double 是一个 64 位浮点数，相当于 Java 的 double 基本类型。如果该值小于或等于 x，则使用<=(x: Long)方法返回 true，否则返回 false。

Method Definition – def <=(x: Long): Boolean

Returns – Returns true if this value is less than or equal to x, false otherwise.

示例 #1：

// Scala program to explain the working 
// of Double <=(x: Long) method
   
// Creating object
object GfG
{ 
   
    // Main method
    def main(args:Array[String])
    {
       
        // Applying <=(x: Long) function
        val result = (12.00123.toDouble).<=(8:Long)
           
        // Displays output
        println(result)
       
    }
} 

输出：

false

示例 #2：

// Scala program to explain the working 
// of Double <=(x: Long) method
   
// Creating object
object GfG
{ 
   
    // Main method
    def main(args:Array[String])
    {
       
        // Applying <=(x: Long) function
        val result = (5.00123.toDouble).<=(13:Long)
           
        // Displays output
        println(result)
       
    }
}

输出：

true
