Description
Hi devs,
This appears to be coded intentionally to behave like this (from reading the Help documentation), but the behaviour itself is simply wrong.
$test=Random(1,1,1) MsgBox(0,@error,$test)
This currently yields 0, presumably because the range is zero. But this is a conceptual mistake.
Consider a vase with a variable (N)umber of balls, numbered consecutively 1-N. If there are three balls (labelled 1,2,3 resp.), my chances of pulling out ball 1 are 1 in 3. If there are two balls, the chance of pulling out ball 1 is 50%. But if the vase contains only ball 1, my chances of pulling out ball 1 are of course 100%, not zero/error.
Exepcted Behaviour: If min=max, return min (or max)
Anything else is counter-intuitive and statistically indefensible.
Cheers,
RT
