Also, I wonder if you’re typing:
5 mod 2
This does give a FlexibleContexts error. You should type either:
mod 5 2 or 5 `mod` 2
(or, using mod’ as suggested):
5.5 `mod'` 1.3

The mod function only works with Integral types, FlexibleContexts wouldn't be helpful for this. On Sat, Feb 20, 2021 at 12:00 PM A.

Is there a better way to use Fractional type than needing to enable FlexibleContexts? What do I need to do to still make use of Haskell's type system, but also still be able to perform operations such as reciprocal (and division into fractions for that matter).
