I need some random numbers.
in the IO Monad, hiding the use of a generator
do x <- randomRIO (0, 1 :: Double) ; print x
you can also make the state explicit:
do g0 <- getStdGen ; let { ( x, g1 ) = randomR ( 0, 1::Double) g0 } ;
print x
a RandomGen is actually the state object for the generator,
much like http://java.sun.com/javase/6/docs/api/java/util/Random.html
best regards, J.W.
