Scala 算术运算符
尝试以下示例程序,以了解Scala编程语言中提供的所有算术运算符。
示例
object Demo {
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) );
}
}
将上述程序保存在 Demo.scala 中。以下命令用于编译和执行此程序。
命令
>scalac Demo.scala
\>scala Demo
输出
a + b = 30
a - b = -10
a * b = 200
b / a = 2
b % a = 0
c % a = 5
