We should allow both fixed and arbitrary precision rational support. - `rat64`: signed 64-bit rational operations building on the [`num_rational` crate](https://crates.io/crates/num_rational) - `bigrat`: signed arbitrary-precision rational operations building on the...
Allow arbitrary fixed-position decimal operations using the [`bigdecimal` crate](https://crates.io/crates/bigdecimal)`.
