The abs()
method in Scala is used to return the absolute value of an integer. The absolute value of an integer is its non-negative value.
The abs()
method can be declared as shown in the code snippet below:
(integer).abs
integer
: The integer whose absolute value is required.The abs()
method returns the absolute value of integer
.
Consider the code snippet below, which demonstrates the use of the abs()
method.
object main {def main(args: Array[String]) = {val n1 = -2;println("(-2).abs: " + (n1).abs);val n2 = 2;println("(2).abs: " + (n2).abs);val n3 = 0;println("(0).abs: " + (n3).abs);val n4 = Double.NaN;println("(NaN).abs: " + (n4).abs);val n5 = Double.NegativeInfinity;println("(NegativeInfinity).abs: " + (n5).abs);val n6 = Double.PositiveInfinity;println("(PositiveInfinity).abs: " + (n6).abs);}}
