Product Description:

MathRPN is really a sweet RPN calculator. Unlike others that limit your ability to interact with the rest of the stack, MathRPN lets you operate on any set of selected stack rows and use your operation of choice. Number formatting preferences and stack autosave complement its functionality, as well as the versatile regular expression engine that allows you to evaluate mathematical expressions in any application, via its service, and use user-defined functions and constants directly with the stack. MathRPN now also includes some graphing support.

What's new in this version:

Order of operations should now be perfect
Ability to select rows from menu items (apple-0 - apple-9) added
User defined functions which are made from other user defined functions should now properly interpret func(x)func(y) as func(x)*func(y), and other such cases.
Other miscellaneous cleanup in preparation for an eventual 1.0 release.

Operating System Requirements:

This product is designed to run on the following operating systems:

Mac OS X 10.4 PPC
Mac OS X 10.3.9
Mac OS X 10.3

course essential, but this problem has several serious problems. 1. on my iBook with the Fn key held down to type in numbers, each number appears twice. 2. when hitting delete, or drop or anything it should show an error status that is not a dialog box because then you have to click enter to get rid of the dialog box, very interrupting.

what I've been looking for in an RPN calculator. One glitch: I had to go into the number preferences and use the "restore defaults" button there before numbers would display correctly. But after I did that it worked great.
