A Web Based Adding Machine

We have Perceptus’ Web Tools at the top of mind lately.  We’ve created another new tool, our minimal web based adding machine.

Have you ever had a half-hazardly formatted list of numbers to add up (maybe from an email?) and you didn’t want to do this:

  • open up Excel (or other spreadsheet program)
  • create a new file
  • paste the values
  • tidy them up so that they are  recognized  as numbers
  • create the SUM() function

Well, we have, and now we have created a tool to save us, and hopefully you, some time.

Visit our new web based adding machine tool and try pasting in a set of numbers like this:

8 000

And be impressed when you get results like this:

Add Running Total
+0 0
+10 10
-7.8 2.2
+8000 8002.2
-92 7910.2
+30.1 7940.3

Impressed?  Did you notice that it handles negative numbers in (brackets) magically?  Or how about that awkward space in “8 000”?  We’re pretty proud of ourselves – even if you’re not impressed.

Comments and feedback is always appreciated!
