pcalc: The Programmer's calculator
There was always a loophole when it came to a need to covert between hexadecimal / decimal / octal / binary.
Especially if it involved an operation like 0x1234 + 0x20. It took a lot of hard work, and mostly a good pocket calculator.
- Full math parser, parentheses, add, sub, mult, div, exponential
- Automatic conversion between HEX DEC OCT BIN numbers
- Mixing different bases in one expression
- Definable variables
- Math constants (E PI ...)
- Built in math functions (sin/cos/sqrt ...)
Here are bunch of common examples.
See the SYNTAX.md file for the full syntax.
You can also run
pcalc for a local reference.
$ pcalc 0x300 768 0x300 0y1100000000 # Note: Shell expansion on the '*' char requires the single quotes. $ pcalc '0x300 + 3 * 3' 777 0x309 0y1100001001 $ pcalc sqrt 2 1.414213562373095 0x1 0y1 # Note: The single quotes are to keep the shell happy with the () characters. $ pcalc 'sqrt(2)' 1.414213562373095 0x1 0y1 $ pcalc 0x12 or 23 23 0x17 0y10111 # To execute a script, use the `@` prefix on the filename. $ pcalc @pcalc.001
Building & Installing
To compile the project, simply use
Note: Some platforms might not provide
You will need to adjust the Makefile accordingly.
To install it, you can do:
$ sudo make install
To run the unittests, use:
$ make check
Note: Depending on the precision of floating point math in your system, some unittests might fail. It's OK to ignore those specific failures.
