3 | * This file is only meant to provide a quick |
---|
4 | * implementation of the output operator. It is |
---|
5 | * provided for test programs that aren't even |
---|
6 | * interested in the precision of the results. |
---|
7 | * A real progam should define its own operators |
---|
8 | * and never include this header. |
