calc.exe - A simple command-line calculator.

calc.zip is a FreeDOS package containing calc.exe (and sources).

To install: fdinst install calc.zip. To install with sources: fdnpkg install-wsrc calc.zip

See calc.txt for documentation and examples.

calc.exe was created to run on (16-bit) FreeDOS, but can also be built to run on (64-bit) Linux. When built on Linux, it is named calq in order to avoid conflicting with the existing (and much more capable) calc command.

calc.exe uses TinyExpr as its calculation engine. tinyexpr.zip contains a subset of the TinyExpr source files that are needed to build calc.exe. The source code for tinyexpr has a separate license.

Building on FreeDOS requires the difpat package to be installed.

On FreeDOS:

>build.bat clean   Remove generated files
>build.bat calc    Build calc.exe
>build.bat pkg     Build FreeDOS package calc.zip

On Linux:

./build.sh clean     Remove generated files
./build.sh calc      Build the calq executable
./build.sh zip       Store files for FreeDOS in c.zip
