F# Syntax Question

A bit of a sytax question...

I have the following code in F#

let GetSumOfSequenceAttempt1 : bigint = 
    seq{bigint(1)..bigint(10000000)}
    |> Seq.sum 

I dont what to keep having to place the numb开发者_StackOverflow中文版ers within the bigint() - is there some shorthand that will make this look neater?

Yes:

let GetSumOfSequenceAttempt1 = 
  seq { 1I .. 10000000I }
  |> Seq.sum
