Free42 vs Scientific Calculator++

Free42 is a re-implementation of the HP-42S calculator and the HP-82240 printer. It is a complete rewrite, not using any HP code, and it does not require an HP-42S ROM image. Free42 is an Open Source project. The executables and source code are released under the terms of the GNU General Public License, version 2. All third-party code used in Free42 is either in the public domain, or licensed under terms compatible with GPLv2, or used with the authors' permission.

The creators of 5-star Scientific++ and Statistics Calculator++ redesigned Scientific Calculator++ exclusively for iPad. Please note that the statistics features that you see in the screen shots are only available through an In-App Purchase. The features that are listed below are all included in the regular purchase of the app. Major features of Scientific Calculator++ are: - Shows the expression as you enter and keeps a history of your calculations. - Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations. - Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format. - Capability of calculating permutation, combination, Least Common Multiple (LCM), Greatest Common Divisor (GCD), and prime factorization. - Quadratic and system of two linear equations solver. - Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers) - Common physical constants can be chosen from a list and used in the calculations. - Throws a set of dice (choice of 1 die to 4 dice) - Backspace to delete last digit entered. - Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians. - Showing the content of memory on MR button, as long as it fits. You are going to love the simplicity of the user interface and yet have the powerful functionality with which Scientific Calculator++ is loaded.
