I've uploaded a new desktop picture, if any of you were interested in checking it out. It is a picture I grabbed from the U.S. Library of Congress's website, and is a gorgeous shot of a B-17 at sunset in 1942.

I also wanted to say thanks a lot for making this year awesome! Since June, PEMDAS has recieved around 5-10 times more downloads than I had ever thought it would. Not only that, but a bunch of people from around the world have spent a lot of time giving some really helpful feedback on how to improve it, which is also really awesome. I may be biased, but I think it's fair to say that PEMDAS is one of the best basic calculators on any platform at the moment, and a large part of that is due to the time other people have put into improving it.

Have a happy new year everyone!

Hey everyone! Now that version 1.0 has been released, the new website is up, and the semseter is finished, I have a lot more time to program. I couldn't help it and changed the look of the 'new' website today, since the original new design was a little dark and not very consistent section-to-section.

I've also been working on version 1.1, which will be the next update to PEMDAS. It will fix a couple interface-related bugs that have been found in version 1.0, as well as a couple other small improvements, and hopefully it will be ready in the next couple weeks. As always, if you have anything you would like to see, let me know.

And finally, I want to wish everyone a happy holidays!

I released version 1.0 this morning (finally!). You can download it by clicking here, or by using the link above. Here are some of the new features of this version:

• New, cleaner look
• Support for variables (by using the equals sign, like a=3*4)
• Programmer Mode
  • Support for entering capital hex letters.
  • Display of binary/hex/octal numbers improved.
• Percentages
  • In a formula, you can type something like 3% and get 0.03
  • A percentage view (next to FLO/SCI/ENG) that will put the answer in percentage form.
• Preference for thousands separators
• Improved support for locales
• Preferences are now saved when restarting your computer
• The widget will check to see if a newer version has been released.
• Exponents are now calculated right to left, not left to right. In other words, 2^3^2 now intprereted as 2^(3^2), not (2^3)^2.
• Precision error tweaking now displays 2.7 and 3.1 in place of of answers like 2.699999999999 and 3.10000000002.

There were also a couple of bug fixes, mostly with the old user interface.

Personally, I think having variables is my favorite new feature in this version, but having the new user interface is also really nice. Like with the last version, a good percentage of the features have come from requests, so if you have a problem or would like to see something, let me know!

Finally, a big thanks goes out to the beta testers, who were a huge help in implementing some of the features, especially the improved support for locales and precision error tweaking. The Apple interface designers I talked to at WWDC were also a big help, and suggested a couple small changes to my original interface design for version 1.0 that made a big difference and really cleaned it up.

Hope everyone likes it, and again, let me know if you have any problems or the widget is missing something you would like to see.

It's 99% finished. There are 70 features and bug fixes in this release, compared to 22 from version 0.92 going to 0.93, not including the new website. Check back in a day or two.
