About PEMDAS Widget
PEMDAS Widget is a simple yet powerful scientific calculator for Dashboard in OS X.
Not only does PEMDAS Widget let you work with equations, variables, different bases, and many different functions, but since it runs in Dashboard, it's very lightweight and is always just a key press away. Best of all, it's free!
Version 3 is a deceptively large update. In addition to adding features like an updated interface and icon, support for retina displays, and better support for mini-mode, it also includes a lot of behind-the-scenes updates that serve as a better foundation for future updates!
Better Mini Mode
It's now easier to get in and out of miniature mode! Just click the '+' button in the lower right corner of the widget!
A Better Foundation
Almost the entire widget interface was rewritten, which will help lay the foundation for future features and help us release updates over the coming months faster.
Retina Display Support
Not only did PEMDAS get an updated look (and looks better than ever!), but it also got support for retina displays in the process! Now it will look nice and crisp on the latest retina Macs.
PEMDAS Widget has many simple yet powerful features. For additional, more in depth information, please see the documentation section.
PEMDAS lets you work with variables. Assigning a variable is straightforward, simply use the equals sign (example: a = 2+2). What's more PEMDAS automatically assigns the result of every equation you calculate to a unique variable, providing easy access to the results of all equations!
Variable Quick Look
When you're typing in a variable name, simply move the mouse over the variable name while holding the Shift key to see the value of the variable!
For Engineers, Scientists, and Programmers
PEMDAS Widget is designed with engineers, scientists, and programmers in mind. Not only can you enter binary, octal, and hex numbers by using the 0b, 0o, and 0x prefixes, format numbers in scientific and engineering notation, and use the percent sign as a modulus operator, but it also supports functions like round(), ciel(), and floor(), as well as the hyperbolic functions.
The most importart feature of PEMDAS is to let you work with equations. Simply type in an equation, hit enter, and you have the answer! There isn't any messing around like with the one-step-at-a-time calculators.
With PEMDAS you can display numbers in floating point notation, scientific and engineering notation, as a percent, and in binary, octal, and hexademical. Additionally, you can limit the number of decimals and significant figures displayed, and turn thousands separators on/off.
PEMDAS Widget runs in Dashboard with all your other widgets, so there's no need to launch an app to do a few quick calculations -- it's always just key press or click away!
Just like PEMDAS Touch
If you've used PEMDAS for the iPhone and iPod Touch, you'll be right at home with PEMDAS Widget (and vice versa!). Both have very similar interfaces and nearly identical feature sets.
