A calculator written in C++ capable of calculating complex expressions
It may be a bit messy because I decided to challenge myself and not really read up on the topic. The only thing I knew before making it is that I would need to create a Abstract Syntax Tree
Currently available operations:
- '+' Addition
- '-' Subtraction
- '*' Multiplication
- '/' Division
- '^' Exponantiation
- '%' Modulus (Only works on integers and negative values are calculated like c++ would by default)
- '!' Factorial (Only works on integers)
Other Features:
- All operations are calculated using 64-bit floats (c++ long double)
- Support for scientific notation (eg. 1e5, 1e+5, 1e-5)
- No need to put * inbetween a number and brackets
- Error Handling
$ ./krecalc "<expression>"For example:
$ ./krecalc "3(4+2) + 3^2 * 3.2e-3"
$ 18.0288- Support for functions like sin(x), ln(x), etc.
- Switch from 64-bit floats to "infnum", a custom data type holding 64 bits of data after the decimal point and a dynamically sized amount of data before the decimal point. Under the hood it works using std::vector
- Proper Error Handling
