Recently , I started learning F# as hobby and started writing some simple programs . Today , I was trying out a sample program in F# which finds out the sum of odd numbers from 0 to 100 in F#.

# How to Find the Sum of odd numbers from 0 to 100 in F# ?

Below is a sample code snippet that does the work.

// Ginktage - F# Program to find the sum of odd numbers from 0 to 100 open System [<EntryPoint>] let main argv = let mutable sum = 0 for indexer=0 to 100 do if indexer%2 <> 0 then sum <- sum + indexer printfn "Sum is %A" sum // Printing the entered input let retval = Console.ReadLine() 0 // return an integer exit code

This solution works, but it’s more like C# than F#, a more idiomatic solution would be to have something like:

[0..100]

|> List.filter (fun i -> (i % 2) 0)

|> List.sum

|> printfn "%i"
