I have a question about how numeric classes and type checking works. I have two
functions that I think should behave the same but don't.
-- I want to split n things up using a given list of fractions
-- for example allocate' 100 [1/3,1/3,1/3]
-- [33,33,33]
allocate' n fs = vs
where vs = map
The important thing is the type of floor:
floor :: (Integral b, RealFrac a) = a - b
That is, if you have a real, fractional type, and you apply floor to
it, you'll get some integral type.
If you look at allocate', you'll see
allocate' :: (RealFrac in, Integral out) = in - [in] - [out]
When you

I mixed up my types when finding the allocated and unallocated,
but I am not sure why it produces an error when unallocated and
allocated are never used? Shouldn't the two functions be compiled
down to the same thing?

Would you consider adding auto-complete feature on Hoogle in the forth

Hi Henning,
For the WWW version of Hoogle this means that data must be transmitted
constantly and I think that rises a privacy problem. I don't want that my
typing behaviour can be observed and analysed somewhere. Such technique
would also require JavaScript which is disabled in browsers

I generally find that I'm wrapping sockets in the same functions a lot
and now I'm looking writings code which works with both Sockets and
SSL connections. So I wrote a module, presumptuously called
Network.Connection, although I'm not actually going to try and take
that name (even in Hackage)

Hello everyone,
While fooling about with generalized tries a night or two ago, I found myself
once again interacting with fixed points of shape functors and the like, and
so decided it was time to finish cabalizing David Menendez' excellent
category theory inspired modules.[1]
So, it is my
Hi,
so let's say I want to generate a list of N random floats. The elegant
way of doing it would be to create an infinite lazy list of floats and
take the first N, but for N = 1,000,000 or more, this overflows the
stack. The reason is apparently that the take function is not
tail-recursive,
