Description​

C++ source file with non-template implementations for the µTest++ expression formatter.

This source file contains the non-template operator<< overloads of expression_formatter for all standard arithmetic, character, string, boolean, and null-pointer types. Each overload appends the formatted value — together with an appropriate type suffix where applicable — to the internal string buffer.

All definitions reside within the micro_os_plus::micro_test_plus namespace.

This file must be included when building the µTest++ library.
