simple-math

Abandoned

simple-math is a badly-named messy piece of crap that doesn't even support compiling to AST before executing.

Alternatives:

• For a binary, check out math-test-haskell. Even though Haskell is probably slower, for this particular project I don't really care.
• For a library, check out calc, maintained by the Redox team and used within the ion shell.

Original README

I was bored, so I made some simple math parser and calculator.

• Arbitrary-length ("big") numbers. (Thanks to library "num")
• Binary/Octal/Hexadecimal numbers
• Bitwise operators
• Factorial
• Function system
• Negative numbers
• Non-whole numbers. (Thanks to library "bigdecimal-rs")
• Orders of operations
• Actually implement some functions

EDIT: Ugh, I can't even make a single project without @tbodt knowing a better solution :P
This time he told me about recursive parsers :O
So yeah, huge thanks to him for being such an awesome person!

simple-math vs GNU bc

After a lot of development, this actually turned out to be a pretty cool project.
Let's compare it to GNU bc!

simple-math cons:

• New technology. Therefore it's currently less stable.
• Power using pow(x, y), not x^y. This is due to the ^ operator doing something else.
• bc is more powerful.
• Probably some more things I don't know about.

simple-math pros:

• Supports factorial built-in.
• No need to struggle with scale=.
• Auto-inserts times where needed (e.g. 2(2 + 2) is 8).
• Supports bitwise operators and bitshifting.
