A very simple calculator written in Brainfuck.
This is a very simple Brainfuck calculator program which supports addition, subtraction, multiplication and division on two positive integral operants.
No input checking is provided. The consequence of wrong input is undefined.
The range of all numbers used in this calculator depends on the given Brainfuck standard of the compiler or interpreter.
The reason behind is that all numbers, including both integer operants and results, are store in one unit of the memory. For instance, given the classic Brainfuck standard whose unit of memory is 1 byte, the range will be 0-255.
The consequences of range overflow is undefined.
Please choose a Brainfuck compiler or interpreter to run the source code.
- Input the first positive integral operant.
42 - Input one of the operants.
42+ - Input the second positive integral operant.
42+8 - Input the equals sign and the result will be outputted after.
42+8=50
100+54=154
Support negative result.
123-89=34
89-123=-34
5*12=60
Support integral remainder.
30/3=10
30/9=3...3
Currently there is no update plan for this Brainfuck program.
Given spare time (and maybe an extremely boring vocation), following update options may be considered:
- Essential input checking
- Larger range for result
- Comment on the source code
