Calculating values with physics unit

Description

This tool is to calculate values that with various physics units. Enjoy your physics homework with it!

Download

Please download from Release Page

Requirement

• libreadline
• c++11 (for regex support)
• cmake (optional, if you want to build with cmake)

Installation

Here are two methods: Calling make directly or using cmake.

Note that we prefer using clang++ than g++

Method 1 - Using 'make':

make
sudo make install

Method 2 - Using cmake:

mkdir build && cd build
cmake -D CMAKE_CXX_COMPILER="/usr/bin/clang++" ..
make
sudo make install

After installation, you should cp consts.txt ~/.bnrc

Usage

To start up this program,just type basicNumeric in your shell after you install it.

A normal mathematical formulas will be recognaized as values. For examples:

• 1 plus 2:

1+2

• Set the value of a variable:

x=1.0

• Set the value of basic unit:

Add a unit 't' in type of mass:

#setUnit t=1000 mass

• Get the value an unit:

%kg

• Set the value of a derived unit:

%N=%kg*%m/%s^2

• Change the default unit to show mass:

#setDefault t mass

• Read commands in file:

#read filename

Changelog

• 1.8(future):

  Add #compare command to compare the value of two variables(done)

  Add #judge command to check a logical experession(done)

  Add #defFunc command to define a user-defined function(done)
