Extension of the Week: Instacalc

The extension I’m focusing on this week is the Instacalc extension. Instacalc is a fast, easy and shareable online calculator. The Instacalc extension will allow you to include a calculator on any Deki page for quick calculations or Advanced Calculations using variables.

To get started install the Math Extension. The configuration/installation of ImageMagick, MiKTeX, and Ghostscript aren’t required to use the Instacalc part of the extension.

Once you have installed the extension you can invoke it by editing the page and clicking on the extension dialog button which looks like this:

This will load the Extension dialog, as seen below, where you can scroll down until you see the Math option, click on that and then select the math.sheet and paste the following url into sheet field:

http://instacalc.com/?d=&c=UHJpY2U9JDMuNzUgLy9Db3N0IHBlciBHYWxsb258RGlzdGFuY2U9MzAwIG1pbGVzIC8v

IE1pbGU9JHIxL3I0fHw&s=sssshss&v=0.9

Then click the Insert Extension button and the following code will be added to your page:

 {{ math.Sheet{sheet: "http://instacalc.com/?d=&c=UHJpY2U9JDMuNzUgLy9Db3N0IHBlciBHYWxsb
258RGlzdGFuY2U9MzAwIG1pbGVzIC8vTWlsZXN8R2FzPSA5IC8vZ2FsbG9uc3xNaWxlcyBwZXIgR2FsbG9uPXIyL3
IzfENvc3QgcGVyIE1pbGU9JHIxL3I0fHw&s=sssshss&v=0.9"} }}

On save this will show the following Instacalc sheet which calculates the cost per mile for your car:
