The GNU Emacs Calculator
************************
“Calc” is an advanced desk calculator and mathematical tool written by
Dave Gillespie that runs as part of the GNU Emacs environment.
This manual, also written (mostly) by Dave Gillespie, is divided into
three major parts: “Getting Started,” the “Calc Tutorial,” and the “Calc
Reference.” The Tutorial introduces all the major aspects of Calculator
use in an easy, hands-on way. The remainder of the manual is a complete
reference to the features of the Calculator.
For help in the Emacs Info system (which you are using to read this
file), type ‘?’. (You can also type ‘h’ to run through a longer Info
tutorial.)
This file documents Calc, the GNU Emacs calculator.
