There are several ways to “program” the Emacs Calculator, depending on the nature of the problem you need to solve.
EvalRules
, they will be applied automatically to all Calc
results in just the same way as an internal “rule” is applied to
evaluate ‘sqrt(9)’ to 3 and so on. See Automatic Rewrites.
Programming features are available through the z and Z
prefix keys. New commands that you define are two-key sequences
beginning with z. Commands for managing these definitions
use the shift-Z prefix. (The Z T (calc-timing
)
command is described elsewhere; see Troubleshooting Commands.
The Z C (calc-user-define-composition
) command is also
described elsewhere; see User-Defined Compositions.)
