Why is hex(255,2) != hex(255,2)?

Why doesn’t this piece of code output anything:

  if(hex(255,2) == hex(255,2)) {
    println("foo");
  }

But this one does?:

  if(unhex(hex(255,2)) == unhex(hex(255,2))) {
    println("bar");
  }

Hello @bbcwarrior.

When comparing strings:

if( hex(255,2).equals( hex(255,2) ) ) {
    println("foo");
  }
