Free42

Free42: One of the best calculus applications for users that work with complex math expressions and precision tasks.

Free42 is a useful utility that was designed to save users the time needed to calculate complex math expressions, based on the powerful HP-42S RPN scientific handheld calculator.

Since the program is portable and doesn’t require installation, users will be able to take it anywhere they want, and another element of surprise is that it sports two calculators, one decimal, and one binary.

Even though it only displays several digits that are influenced by the function buttons that the users combine, it also allows them to put the results to good use, which means, export options enable them to save expressions in order to import and process them later, while even offering options to automatically have a log of operations saved to a text file.

Users will also be able to get ahold of a GIF file with the same info, copy the values and quickly insert them wherever they need, and is also capable of processing, sin, cos, tan, conversions, sums, etc.

Free42 is one of the best applications out there for users that need to do many complex calculus and precision tasks.
