Calculator Specific Problems, Questions, or Feedback

Please note that the contact form on this page is for questions and feedback related to the website in general. Calculator specific problems, questions, and feedback can be submitted in one of the following ways, depending on whether you are using a web app on this site, or a native app on your phone or tablet.

  • Web App Calculator: Go to the calculator and submit your question via the feedback form located beneath the calculator.
  • Native App Calculator: Use the feedback form included in the app.

If you try to submit a calculator specific support request on this page, I will have no way of knowing which calculator on which platform you are referring to.

And just so you know, I will never give or sell your e-mail address to anyone and I promise not to send you any unsolicited email (I hate spam too!). If you do or don't want a reply, please state your case in your message.

Highlights and Features

Highlights and Features:

Top 10s: this tab for an introduction to this section.

Articles: this tab for links to various articles that are included on the calculator pages.

Guide: this tab for instructions on how to use this website.

Pocket Calc: this tab for a handy "pocket" calculator.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
