$value=rand(0,0);

Gives "Warning: rand(): Invalid range: 0..0 in ..." while there is nothing wrong with it. Value shouldn't be invalid.

I'm expecting a value of 0 with probability of 100% without any warnings or is this a feature?

It's not a bug, it's clear that this was supposed not to work. And if you try rand (1,1) it wont work either.
Another thing; I don't see why this would be usefull.

After an e-mail comversation, Jukka made it clear it is useful, so I commit a "fix" to the CVS
