/* 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.
