I’m certain that you’ve found at least 3 awesome online calculators today. Do you have alternatives that are awesome enough to be added to the list? Feel free to add your suggestions in the comments section below.

Only one of the solutions listed had the ability to set the display places and that one didn’t have the ability to paste values in. I’ll keep looking for an online solution that will let me paste values in, do operations and get solutions to two places (ie simple monetary calculations) and then cut the solution and paste into another app.

It was surprising to me how many of the online calculator solutions don’t have the ability to paste a value. Seems to defeat a lot of the utility of an online solution.
