Hi
I have tried I swear, even googled for 45 minutes, but I cant seem to get random numbers working.
In the documentation is has:
rollDice :: IO Int rollDice = getStdRandom (randomR (1,6))
But if I type "getStdRandom (randomR (1,6))" into hugs in the context of module which imports Random, I get get errors.
ERROR - Unresolved overloading *** Type : (Random a, Num a) => IO a *** Expression : getStdRandom (randomR (1,6))
Roll dice takes no parameters and returns an IO Int. So in thoery (mine at least ;-) ) running this as an expresion should work. I should get an IO Int back from the interpreter ?
So I added RollDice to my module. This doesnt error, but it doesnt return anything except blank spaces:
HasGal> rollDice
HasGal>
Integers or nums should automatically have show correct? So this should show me something ?
Ultimatly I want to get randomRs infinite list working so I can build
randNums = (take (length popList) [1..])
where the length of pop list is how many random numbers I want. My code works as it, just need to replace [1..] with some random numbers.
Thanks,
C
