Coverage Summary for Class: HackersDelightKt (dev.suresh.lang)

 package dev.suresh.lang
 
 const val HAS_SEMI = 0x3B_3B_3B_3B_3B_3B_3B_3BL
 
 /**
  * Has a zero byte in a long, copied straight from
  * [Hackers Delight](https://doc.lagout.org/security/Hackers%20Delight.pdf)
  *
  * Unlike in Java, hexadecimal integer literals in Kotlin can't represent negative values. So we
  * have to use [ULong] for literal values greater than [Long.MAX_VALUE]
  *
  * Eg:
  * ```kotlin
  *     val long = 0x80_80_80_80_80_80_80_80u.toLong()
  *     println(long.toString(16))
  *     println(long.toString(2))
  *     println(long.toULong().toString(16))
  *     println(long.toULong().toString(2))
  * ```
  *
