The calculator included with Windows CE is a basic four-function calculator with memory and a pseudo paper tape display. This is sufficient for many users, but if you need to do scientific or business calculating, a more advanced calculator is a must. Odyssey Computing provides such a calculator with Pocket BizCalc, a Windows CE and Windows 95 calculator program that emulates the popular HP-12C calculator.
Installation is a two-step process.
Installation automatically creates an icon for the program. The 12C supports only 99 programming steps, BizCalc users can create and save programs with up to 999 steps. The tape register allows for either tape, memory, or register views. In addition to all of the built-in HP 12C functions, Pocket BizCalc also includes several functions that are available on the 12C, but require multiple keystrokes to accomplish. This includes several business functions and a key to calculate pi.
