This is a terminal app for math expressions calculation. It allows to make calculation fast right in your console, like:

calc "5.4 * 3,000.02 - 5*2 + 3! - (4+5) + sin 0 - cos PI"

See GNU GPLv3 LICENSE.txt

(tested on macOs 10.15.2 with openJDK 11)

Make sure you have jdk and xcode installed. Run the following command in terminal ./gradlew :macosBinaries After compilation you will find your executable in build/bin/macos/releaseExecutable

(tested on ubuntu 18.04 x64 with openJDK 11)

Make sure you have jdk installed. Run the following command in terminal ./gradlew :linuxBinaries After compilation you will find your executable in build/bin/linux/releaseExecutable

(tested on windows 10 x64 with openJDK 11)

Make sure you have jdk installed. Run the following command in terminal .\gradlew.bat :windowsBinaries After compilation you will find your executable in build\bin\windows\releaseExecutable

Make sure your executable is reachable in PATH. In case it is not you have 2 choices:

• You can move it to some of the directories from PATH (for example /usr/local/bin/)
• You can add the folder where executable is located to your PATH

feel free to rename executable to make it more convenient for you

This app can process the following operators (ordered by priority):

1. (,)
2. ! (factorial), ^ (power), v (square root)
3. ln (logarithm base e), log (logarithm base 10), sin, cos, tg/tan
4. */x, /
5. -, +

• PI
• e

In simple cases you don't need to put brackets. The app will try to parse an expression using the predefined priority of operators.

• calc "5 + 6 * 2" will be parsed like 5+(6*2)
• calc "5 (6 * 2)" will be parsed like 5*(6*2)
• calc "sin cos 0" will be parsed like sin(cos(0))
• calc "5 + 4 * 2!" will be parsed like 5+(4*(2!))

If you not sure about priority fill free to use brackets:

• calc "(5 + 6) * 2" will be parsed like (5+6)*2
• calc "((v3) * 2) / (5!)"
