Almost because of the King of the slave tool to the Master Tool, inspired by the letter, the heart of the creation, then made a calculator, named in the Abacus: abacus, is released in this community, seen in http://www.oschina.net/code/snippet_736932_13725, what's the beauty of it? Wait for me to say:
1. supports regular four-digit hybrid operations
2. Supports many mathematical functions. For a list of functions, see the software help.
3. symbol constants are supported, such as the base number of the circumference rate and natural logarithm.
4. Good design, easy to add new operators and new mathematical functions
5. Complete information and input h or help to view help information at any time during program operation.
Based on the above items, it can replace the system's self-generated calculator, and its functions have never been inferior. With its open-source power, anyone can make it fit their own aspirations. Welcome and make suggestions!
