ratio library

Header-only, constexpr library providing exact representation for rational numbers.

Relative to std::ratio:

1. Uses constexpr instead of creating new types. This means it can be used seamlessly at runtime.
2. Supports a few more arithmetic operations, for example exponentiation to integer powers.
3. Provides constexpr conversion to fixed-capacity strings (using xo-flatstring)
4. Provides concept support (with c++20)
5. Requires modern (c++17) support to achieve this

Getting Started

install dependencies

• github/Rconybea/xo-cmake cmake macros
• github/Rconybea/xo-flatstring fixed-capacity strings

build + install

$ cd xo-ratio
$ PREFIX=/usr/local # for example
$ BUILDDIR=.build   # for example
$ make ${BUILDDIR}
$ cmake -DCMAKE_PREFIX_PATH=${PREFIX} -B ${BUILDDIR}
