[section:complex Complex Number Types]

The following backends provide complex number arithmetic:

[table
[[Backend Type][Header][Radix][Dependencies][Pros][Cons]]
[[`cpp_complex`][boost/multiprecision/cpp_complex.hpp][2][None][An all C++ Boost-licensed implementation.][Slower than [mpc].]]
[[`mpc`][boost/multiprecision/mpc.hpp][2][[mpc]][Very fast and efficient back-end.][Dependency on LGLP-licensed [MPC] library.]]
[[`complex128`][boost/multiprecision/complex128.hpp][2][`__float128` and libquadmath][Very fast and efficient number type.][128-bit precision only, and restricted to GCC.]]
[[`complex_adaptor`][boost/multiprecision/complex_adaptor.hpp][-][none][Can convert any backend type into a complex number backend.][Not a number in its own right, and hard to use as a result.]]
