---------------------------------+------------------------------------------
Recently I was using the standard random number generator and found it
that the program was breaking with an array index out of range.
I was using the Float data type not Double. The range was the basic (0,1)
range. The test code is the following.
test :: Float
test = let gen = read "1005320695 588518561" :: StdGen
in fst $ random gen
