  The versions of rand() and srand() in the Linux C Library use the same
  random number generator as random() and srandom(), so the lower-order
  bits should be as random as the higher-order bits.  However, on older
  rand() implementations, and on current implementations on different
  systems, the lower-order bits are much less random than the higher-
  order bits.

And even that doesn't matter unless you use only the lower bits.
There is certainly no difference in the distribution if you divide
by RAND_MAX to a [0...1] float result.
