[section:rational Rational Number Types]
The following back-ends provide rational number arithmetic:
[table
[[Backend Type][Header][Radix][Dependencies][Pros][Cons]]
[[`cpp_rational`][boost/multiprecision/cpp_int.hpp][2][None][An all C++ Boost-licensed implementation.][Slower than [gmp].]]
[[`gmp_rational`][boost/multiprecision/gmp.hpp][2][[gmp]][Very fast and efficient back-end.][Dependency on GNU licensed [gmp] library.]]
[[`tommath_rational`][boost/multiprecision/tommath.hpp][2][[tommath]][All C/C++ implementation that's Boost Software Licence compatible.][Slower than [gmp].]]
[[`rational_adaptor`][boost/multiprecision/rational_adaptor.hpp][N/A][none][All C++ adaptor that allows any integer back-end type to be used as a rational type.][Requires an underlying integer back-end type.]]
[[`boost::rational`][boost/rational.hpp][N/A][None][A C++ rational number type that can used with any `number` integer type.][The expression templates used by `number` end up being "hidden" inside `boost::rational`: performance may well suffer as a result.]]
