fun main() {

    val floatValue = 123.23452F
    val floatValueRoundedOff = 1.234278690234f
    println(floatValueRoundedOff) // since float has only 7 to 6 decimals, value of f is rounded to 7 decimal point

    // declaring Int value as hex

    // declaring long value as bytes
    val bytes: Long = 0b11010010_01101001_10010100_10010010
