Tc calculator (extension) Extension

Simple offline BC-like calculator for programmers with support for user defined functions and history.

Technetium (Tc) is calculator. It works completely offline. It is very similar to BC command line calculator in a sense that there are no buttons (like in XCalc) but you simply type expression you want to evaluate. Tc use JS for evaluation so you can use almost any valid JS code. You can write your own library of functions. You can open it in popup or in multiple tabs. There is also extensive offline help included. There are over 60 built in functions.

This is extension version. Tc is also available as Chrome packaged app (for chromebooks).

Peter Scarth (ID: 000000eb954b7b7b) Voted 5 ★ - Updated 11/14/2018 I'm so happy to see this excellent calculator as an extension. Works as a popup for quick calculations or in it's own tab for bigger jobs. And needs no special permissions. The calculator I've been looking for.
