a41cv is my open source simulator of the legendary HP41CV RPN calculator. The first production version of a41cv was released in February 2011. Nearly all of the original HP41CV functions are implemented.

The calculator differs from the HP41CV in the following ways:

No definition of number of register

Programmes cannot be assigned to keys (working on that)

Not all special flags implemented

Number of programme lines only limited by phone memory

Only a simple programme editor (by now) but full import / export of programmes on cvs format

Still trying to make a41CV fit better on the now more than 1782 different devices it works on according to Google Market

此版本中的新功能：

Not much news in version 1.5.

Some bugs have been solved and the old layout removed as it was too dependent on screen size. This reduced the size of the app to a 1/4 of last version.

Bug fixes:

Problem with rounding in INT function solved

Problem with stack lost when the user switch to other apps solved
