This section is a summary of all symbols that can appear on the Calc mode line, the highlighted bar that appears under the Calc stack window (or under an editing window in Embedded mode).
The basic mode line format is:
--%*-Calc: 12 Deg other modes (Calculator)
The ‘%*’ indicates that the buffer is “read-only”; it shows that regular Emacs commands are not allowed to edit the stack buffer as if it were text.
The word ‘Calc:’ changes to ‘CalcEmbed:’ if Embedded mode is enabled. The words after this describe the various Calc modes that are in effect.
The first mode is always the current precision, an integer.
The second mode is always the angular mode, either
