It is between 0 and 1.

For value between 1 and 5 use following expression:
(rand()+1)*4

For this you will have to feed seed function with random number, but
question is, how this random number will be generated?  To my knowledge
there is no easy way to accomplish it.
But is it good idea at all: if you got what you want, then how will you
know, what was exact value of random number in order to repeat it? ;-)

You welcome. But reading a manual will help a lot and will give answer
to some questions (e.g. rand() output limits).
