[section:ints Integer Types]
The following back-ends provide integer arithmetic:
[table
[[Backend Type][Header][Radix][Dependencies][Pros][Cons]]
[[`cpp_int`][boost/multiprecision/cpp_int.hpp][2][None]
[Very versatile, Boost licensed, all C++ integer type which support both [@http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic arbitrary precision] and fixed precision integer types.][Slower than [gmp], though typically not as slow as [tommath]]]
[[`gmp_int`][boost/multiprecision/gmp.hpp][2][[gmp]][Very fast and efficient back-end.][Dependency on GNU licensed [gmp] library.]]
[[`tom_int`][boost/multiprecision/tommath.hpp][2][[tommath]][Public domain back-end with no licence restrictions.][Slower than [gmp].]]
