/* Boost interval/io.hpp header file |
|
* |
|
* This file is only meant to provide a quick |
|
* implementation of the output operator. It is |
|
* provided for test programs that aren't even |
|
* interested in the precision of the results. |
|
* A real progam should define its own operators |
|
* and never include this header. |
