 The class `underflow_error` defines the type of objects thrown as
 exceptions to report an arithmetic underflow error.
 ``` cpp
-underflow_error(const string& what_arg);
 ```
 *Ensures:* `strcmp(what(), what_arg.c_str()) == 0`.
 ``` cpp
-underflow_error(const char* what_arg);
 ```
 *Ensures:* `strcmp(what(), what_arg) == 0`.
