Total Functional Programming
- Total functional programming excludes the possibility of non-termination.
fibfunction will not compile in Haskell 2010 due to later standard not supporting
n + kpatterns.
- Haskell 2010 version can be writen as follows,fib n| n == 0 = 0| n == 1 = 1| otherwise = fib (n-1) + fib (n - 2)
- In a non total language, each type contains a
- In a non-total language such as Haskell, even simple natural identity such as
e - e = 0cannot be assumed to hold true equationally due to the presence of
