Question

How to get the lower 8 bits of an int in Scala

Answer 1

object BitManipulation {
  def printBinary(n: Int, width: Int): String = {
    val binary = n.toBinaryString
    "0" * (width - binary.length) + binary
  }

  def main(args: Array[String]): Unit = {
    val n = 1957

    // Print 16-bit binary representation
    println(printBinary(n, 16))

    // Extract low 8 bits
    val low8bits = n & 0xFF
    println(printBinary(low8bits, 16)) // Also padded to 16 bits
  }
}
