|
|
* @file base_units.cpp
|
|
* @brief Code to handle objects that require both schematic and board internal units.
|
|
* @note This file is an ugly hack to solve the problem of formatting the base units
|
|
* for either schematics or boards in objects that are include in both domains.
|
|
* At some point in the future. This code should be rolled back into the
|
|
* appropriate object and build with the correct internal unit formatting
|
|
* depending on the application.
