please excuse my late reply. I’ve been busy working, to be able to finance my work on this and other projects.

A fractions button is a good idea. However, to be able to use the calculator as a fractions calculator there would be a lot more needed than a fractions button. I would also have to figure out a way to input fractions and a way to display the result in fractions. This might be best done with a new tab. I will put this feature on the wish list and try to realize it next time I work on the calculator.

In the mean time, you might try searching for an online fractions calculator with a search engine. There are few usable ones out there.

Thanks again!

Thanks!

I’m glad you find the calculator useful. The problem you report is strange – I have not been able to recreate it. I suspect the storage of your saved settings and numbers has become corrupted. If you don’t mind losing your saved numbers and settings, you might try deleting your settings under the options (o) tab. If you don’t want to lose your saved settings and numbers, you might also try to change your decimal separator, also under the options tab. Please write me an email at marek@calculator-tab.com about whether this has worked for you.

However, there seems to be a bug in the calculation of trigonometric functions. I input 60, click the left hand ‘f’ button and then click ‘sin’ I get ’0undefined866….’. Same error for ‘cos’ and ‘tan’.

I’m running Firefox 3.5.7 under Windows XP.

there already is a button for pi. It is on the left tab labeled with “f” for functions and is the 3rd button from the left in the bottom row.

If the two buttons for percent on the bottom tab don’t suite your needs, you might want to try the percent button on the test drive page. Using it you can make calculations like 50 + 10%.

I’m sorry that the calculator does not work for you. It’s strange, that you can see the calculator, but cannot press the buttons. If you let me know what your operating system, your browser and your flash version is, I will look into it.
