Engineering Calculator ====================== | Author: Ken Kundert | Date: 2022-12-27 | Version: 1.10 This calculator is noteworthy in that it employs a stack model of computation (Reverse Polish Notation), it supports numbers with SI scale factors and units, and uses a text-only user interface. Installing ---------- Requires Python version 3.6 or later. Install with:: pip install --user engineering-calculator This installs *ec* into ~/.local/bin, which should be added to your path. Unusually, there is also a man page. The Python install process no longer supports man pages, however you can download it from `its Github repository `_. Place it in ``~/.local/man/man1``. Features -------- - Text-based interactive interface. - Stack-based calculation model - Full scientific/engineering calculator. - Support SI scale factors and units on inputs and outputs. - Supports hexadecimal, octal, and binary formats in both programmers and Verilog notation. - Provides special functionality for electrical engineers. Examples -------- Invoke engineering calculator and compute the value of a resistor by dividing the voltage difference across the resistor by the current through it:: > ec 0: 2.5V 250mV - 1mA / 2.25k: Here a hexadecimal number is converted to and from decimal:: > ec 0: 'hFF 255: vhex 'h00ff: In this example, a frequency is converted to radians and saved into the variable *omega*, which is then used to compute the impedance of an inductor and capacitor:: > ec 0: 1MHz 2pi * =omega 6.2832M: 100nH * 628.32m: 1 10nF omega * / 15.915: Issues ------ Please ask questions or report problems on `Github `_.
