...when you have a value eg 22 which is made up of 2+4+16 so you know of all your options valued 2,4,8,16,32 Etc only 2 and 4 and 16 apply.
I know there must be a mathematical name for this, but what? Does anyone have some example CF code to 'decrypt' such numbers? Are there other [simple] ways to do this to handle a large number of options (>25, so I don't start having giant numbers?) Something to do with prime numbers perhaps? You can tell I'm not a mathmatician can't you!
