> Yes, rationals with arbitrary precision are more expensive to compute with than precision-limited floats. But who cares? It is not the 80s anymore.
The people who care are the people who now either have to buy 10000× the computing power or solve only 1/10000× the largest problem size to solve their needs, usually without meaningfully improving their results. Put another way, using rationals would turn your 2020-era computer into a 1980-era computer in terms of performance on your linear algebra benchmarks.
