Installation: Download JCalc_.class to the plugins folder, or subfolder, restart ImageJ, and there will be a new "JCalc" command in the Plugins menu, or submenu.
Source: JCalc_.java
Problems: The last button clicked is highlighted (e.g., the "Sqrt" button in the illustrations).

Keyboard input is supported using the following shortcuts: 

    q - SQRT
    s - SQR
    l - Log
    x - 1/X
    p - pi
    space - Clear
Like PlugInFrames built into ImageJ (e.g., Image/Adjust/Threshold), it calls WindowManager.addWindow() to add itself to ImageJ's Window menu and maintains a variable named instance to prevent opening of multiple copies.

JCalc is based on Mikael Bonnier's Pocket Calculator applet.
