...one of the most highly
regarded and expertly designed C++ library projects in the
world.

boost/multiprecision/gmp.hpp |
2 |
Very fast and efficient back-end. |
Dependency on GNU licensed GMP library. |
|
|
boost/multiprecision/mpfr.hpp |
2 |
Very fast and efficient back-end, with its own standard library implementation. |
||
|
boost/multiprecision/float128.hpp |
2 |
Either libquadmath or the Intel C++ Math library. |
Very fast and efficient back-end for 128-bit floating-point values (113-bit mantissa, equivalent to FORTRAN's QUAD real) |
Depends on the compiler being either recent GCC or Intel C++ versions. |
