by Marcus Green.   Thanks Martin, floor was an excellent clue I now have this in the question variables start:1/2 + rand_with_step(0,8,1); wholepart: floor(start); fractionalpart: start - wholepart; And  this in the question text {@wholepart@} {@fractionalpart@} And it appears to do what I wanted ..read more

by AL Rachels.   I never did very much with STACK, and right now trying to set up Rock 9 Linux, I seem to find that it is impossible to install all the dependencies needed to run it. I am beginning to think I need to drop it like a hot "Rock"y and start over with Ubuntu, as I do have multiple small board computers with STACK working on them, albeit slowly compared to my big server ..read more

However, I don't want the hints to be visible during the exam, but I do want to show students if their answer is correct (I use quiz Adaptive mode).
