Answer 1

You can use the F# Powerpack which has a BigRational (arbitrary precision rational numbers) type:

let r = (1N/2N) * (1N/3N) // 1/6

Hi Gabe, is this something that's still viable, or do you know if its been replaced by new F# features? – Stria

@JimDel: As far as I know, Powerpack is still the way to go. – Purree

According to the F# PowerPack archive on GitHub README, BigRational is present in F# support in Math.Net Numerics – Arrearage

Answer 2
