Example
The code snippet below demonstrates the use of the floor() method:
object main {def main(args: Array[String]) = {val n1 = -2.5;println("(-2.5).floor: " + (n1).floor);val n2 = -2.2;println("(-2.2).floor: " + (n2).floor);val n3 = 0;println("(0).floor: " + (n3).floor);val n4 = 3.9;println("(3.9).floor: " + (n4).floor);val n5 = 3.1;println("(3.1).floor: " + (n5).floor);}}
