### NAME

clarence - programmer’s scientific calculator for X

### SYNOPSIS

clarence.py [-h] [--help] [-v] [--version] [-m] [--disable-menu]

### DESCRIPTION

Clarence is a programmer’s scientific calculator writen in Python. It has gui based on PyGTK, uses all Python’s operators, math module functions and constants. It can handle all basic numerical formats including Dec, Hex, Bin, Oct, and ASCII. Expressions can be entered in an entry field without mouse operations (no more buttons).

### OPERATIONS

Avaiable operators, functions and constants:

or - Boolean OR

and - Boolean AND

not x - Boolean NOT

| - Bitwise OR

^ - Bitwise XOR

& - Bitwise AND

~x - Bitwise NOT

<<, >> - Shifts

- - Subtraction

* - Multiplication

/ - Division

% - Remainder

** - Exponentiation
