試試下麵的例子就明白了所有Scala編程語言中可用的算術運算符。複製並粘貼以下Scala程序在Test.scala文件中,編譯並運行此程序。

object Test {
   def main(args: Array[String]) {
      var a = 10;
      var b = 20;
      var c = 25;
      var d = 25;
      println("a + b = " + (a + b) );
      println("a - b = " + (a - b) );
      println("a * b = " + (a * b) );
      println("b / a = " + (b / a) );
      println("b % a = " + (b % a) );
      println("c % a = " + (c % a) );
      
   }
}

這將產生以下結果：

C:/>scalac Test.scala
C:/>scala Test
a + b = 30
a - b = -10
a * b = 200
b / a = 2
b % a = 0
c % a = 5

C:/>
