Scala - Math toIntExact() Method



The Scala Math toIntExact() method returns the value of the Long argument. The method throws an exception if the value of the argument overflows an Int.

Syntax

def toIntExact(x: Long): Int = java.lang.Math.toIntExact(x)

Parameters

x Specify the long value.

Return Value

Returns the value of the Long argument. Throws an exception if the value overflows an Int.

Exception

throws ArithmeticException, if the argument overflows an Int.

Example:

In the example below, Math.toIntExact() method returns the value of the Long argument.

object MainObject {
  def main(args: Array[String]) {
    var x : Long = 100;
    var y : Long = Int.MaxValue;
    println("Math.toIntExact(x) = "
            + Math.toIntExact(x)); 
    println("Math.toIntExact(y) = "
            + Math.toIntExact(y)); 
  }
}

The output of the above code will be:

Math.toIntExact(x) = 100
Math.toIntExact(y) = 2147483647
