Idiomatic Scala error handling

SquareRoot.scala

import scala.util.{Failure, Success, Try}

def squareRoot(value: Int): Try[Double] = {
  if (value >= 0) {
    Success(Math.sqrt(value))
  } else {
    Failure(new IllegalArgumentException("Value cannot be negative"))
  }
}
val sum = for {
  a <- squareRoot(4)
  b <- squareRoot(16)
} yield a + b
sum.map(s => s"The result is $s") match {
  case Success(result) => result
  case Failure(t) => t.getMessage
}
