Visual calculator for bitwise expressions
Bitwise operations in C and other derivative languages can be a bit
challenging to visualize and understand if you don’t use them very often.
Now, you can use this simple expression calculator to see a visual
representation of the bitwise operations to verify your intuition or to
learn.
Bitcalc supports all standard C bitwise operators (<<, >>, &, |,^, and ~) and the basic C arithmetic operators (+, -, *, /, and%). All of the supported operators follow standard C precedence and
associativity rules. Operator precedence can be changed using parentheses,
as is typically permitted in C.
Bitcalc can be installed easily using pip:
pip install https://github.com/chrisrink10/bitcalc
You can start bitcalc from your console using the bitcalc command.
Simple operations show the bitwise operation in the format typically used
by students learning basic arithmetic operations to help clarify what is
happening at a bit level.
>>> (1 | 10)(1 | 10)00000001| 00001010------------0000101111
More complex expressions are solved one-by-one in order of precedence for
each sub-expression to help make clear how each operand in the final
expression was calculated.
>>> (81 & (1 << 3))(1 << 3)00000001<< 3------------00001000(81 & (1 << 3))01010001& 00001000------------000000000
Bitcalc supports arbitrary complex expressions.
>>> (81 & (1 << 3)) | (45 ^ (3 << 2))(1 << 3)00000001<< 3------------00001000(81 & (1 << 3))01010001& 00001000------------00000000(3 << 2)00000011<< 2------------00001100(45 ^ (3 << 2))00101101^ 00001100------------00100001((81 & (1 << 3)) | (45 ^ (3 << 2)))00000000| 00100001------------0010000133
