  • num: The number whose ceil value is required.

Return value

The ceil() method returns the ceil value of a number by rounding up the number.

Example

The code snippet below demonstrates the use of the ceil() method:

object main {
def main(args: Array[String]) = {
val n1 = -2.5;
println("(-2.5).ceil: " + (n1).ceil);
val n2 = -2.2;
println("(-2.2).ceil: " + (n2).ceil);
val n3 = 0;
println("(0).ceil: " + (n3).ceil);
val n4 = 3.9;
println("(3.9).ceil: " + (n4).ceil);
val n5 = 3.1;
println("(3.1).ceil: " + (n5).ceil);
}
