This directory contains examples of Bison grammar files.
Most of them come from the documentation, which should be installed together
with Bison. The URLs are provided for convenience.
# rpcalc - Reverse Polish Notation Calculator
The first example is that of a simple double-precision Reverse Polish
Notation calculator (a calculator using postfix operators). This example
provides a good starting point, since operator precedence is not an issue.
Extracted from the documentation: "Reverse Polish Notation Calculator"

# mfcalc - Multi-Function Calculator
A more complete C example: a multi-function calculator.
Extracted from the documentation: "Multi-Function Calculator: mfcalc".
https://www.gnu.org/software/bison/manual/html_node/Multi_002dfunction-Calc.html
