GlassCalc is a calculator for Windows that, unlike many other calculator programs, has no buttons. Instead, it has a single textbox where you can type an equation or mathematical expression, hit Enter, and get a result. This is often much faster than the hunt-and-peck method of clicking buttons. The lack of buttons also leaves plenty of room for a full history of past equations (calculator tape), a reference listing of all available functions, and a list of user-defined variables and functions.
The name, "GlassCalc" comes from my total lack of inspiration, the extra bit of Aero glass, and a Google search page that didn't show any results for "GlassCalc" that were software calculators. I started making GlassCalc when I discovered that the Microsoft PowerToy Calculator didn't work properly in Windows Vista/7 without administrative privileges. I wanted a calculator that I could quickly type equations into without getting a UAC prompt every time I started it.
GlassCalc uses Mathieu Jacques' MTParser and a bunch of regex magic to parse and evaluate equations. It is capable of (but not limited to) the following:

System Requirements
In theory, all you need is a Windows machine with the .NET Framework 3.5. I have only tested this on a Windows 7 and an XP machine, but it should work on Vista and earlier versions of Windows.
If a previous version of GlassCalc worked on your computer, click the "Upgrade" link below. The regular installer includes the Visual C++ 2005 libraries, which you don't need to download again if they are already installed. If GlassCalc won't run, please fill out a bug report with the link at the bottom and I will do my best to fix the problem.
