It uses 3 files, but has no dependencies, and runs even on stupid and weirdly restricted environments like repl.it.
math::Rational depends on math::Integer which depends on math::Unsigned, but they're only 1 file each. It's a really good arbitrary-precision library for stuff that doesn't need irrational numbers.
