Scientific Expression Calculator

The most versatile scientific calculator for the iPad and no in-app purchases! Now with query/assignment variables, user defined functions & constants, Dropbox, and TextExpander support. Expression, RPN & Algebraic modes. The scratchpad for notes, and evaluating equations without the calculator. So many features; d/l the free manual to learn about them before purchase (see link below). Important changes; check the What's New list. New features to come -> watch for updates.

Use the scratchpad to work on problems, create and store equations and notes. Evaluate equations within the scratchpad; Just type two = signs after the equation or use gestures, and the scratchpad figures out where the notes end, and the equation begins, adding the solution to your notes. Many, many more functions and constants available in scratchpad equations. The scratchpad text can be synchronized to your Dropbox account.

The calculator has many built-in functions, constants and visual memory storage and recall. Define your own constants and functions.

The Expression mode of the calculator allows you to input an entire equation before evaluation. This is a great advantage whether adding a series of numbers or evaluating a complex trigonometric equation.

The RPN or Reverse Polish Notation mode is loved by many calculator users for efficiency. The Algebraic mode is familiar to users, the standard mode on most calculators.

The paper tape tracks your input and results, and can be hidden.

The Scientific Expression Calculator is a great calculator for students, engineers and scientists. Comments, questions and problems can be sent to "iOS@azarhi.com".

Download the free PDF manual by going to http://www.scicalcapp.com/ The manual is great for learning about all of the features, and the many functions available in the scratchpad.
