EasyCalc is a graphing, scientific calculator for Palms and PalmPilots. Of course it has all the capabilities and ease-of-use of the built-in "4-Banger" that comes with the PalmPilot, but also includes trigonometric functions, financial functions, complex numbers and graphing. In addition, you can define your own functions and variables with names up to 10 characters long and nesting up to ten levels deep. Values may range between 1E-100 and 1E..
