I am trying to define the following types
data MyStringType a = String deriving (Eq, Ord, Show)
data QADouble a = Double deriving (Eq, Ord, Show)
data HType a = QADouble a| DDTraceType a deriving (Eq, Ord, Show)
So HType can represent strings or doubles.
later I want to do something like the
Suppose there is a data definition in Haskell:
data MyType = MyType { date :: Double,
weight :: Double,
height:: Double
} deriving (Eq, Ord, Show)
Is it possible to check if the field height, for example, is filled
Fibonacci numbers implementations in Haskell one of the classical examples.
An example I found is the following:
fibs :: [Int]
fibs = 0 : 1 : [ a + b | (a, b) - zip fibs (tail fibs)]
To get the k-th number you do the following:
Result = fibs !! k
It is elegant but creates a list of all
Hello ALL,
I am very new to Haskell and my question might appear very basic sorry about
it in advance.
I have a C++ application and I would like to be able to launch Haskell
interpreter (lets say GHC) supplying the Haskell code (in a file ) to be
interpreted from it. The Haskell program
