bit is of bool type. I checked with ILSpy and there's an explicit cast added in one of closures generated.
I decided to use F# to solve the second problem for the first day of Advent of Code 2018 (performing a cyclic summation and finding the first repeated sum) in an expressive manner, but the performance is lacking and I can't find the cause of the slowdown.
It seems like there are two ways to return errors in an async workflow: raise and Result. For the caller, the handling is a bit different:
When writing a function that can accept currying, you can write it as a single-argument function that returns a function. For example,
Apologies for a rookie question. I'm trying to change my mental paradigm from procedural to functional.
I set myself the following challenge (and failed):I want to write a map functional, map f lofls, that takes a function, f 'a -> 'b and a list of lists, lofls 'a list list and applies the function f on every element of the list of lists. The constraint that...
In Python, I could see the variable's type by typing:Is there a way to do this in F#?If you're wanting to do this in F# Interactive, you just need to evaluate the variable by typing its name (followed by ;; as with any other expression at the F# Interactive prompt)....
If I have a function that is part of a module, and I want a log entry while inside the function,I have to manually print the function namespace and name e.g.
Type signature of Haskell's bind operator (>>=):Type signature of F#'s forward pipe operator (|>):They look similar. And considering the impure nature of F#, the equivalent operator of |> in Haskell is >>=?
C# 7.0 introduced value tuples and also some language level support for them. They added the support of single and zero element tuples as well; however, I could not find out any scenario when they could be useful.
