Kal Pro v1.9

Requirements: 2.2+

Overview: It is a very complete scientific calculator, contains most mathematical functions with the ability to perform graphics functions.

It includes a library with one hundred (100) formulas of mathematics and physics ready to use, which generates a result after entering the value of its variables, it also allows to easily extend the library with your own formulas or functions, in general is very easy to use like a real calculator, includes a display for writing operations without character limit, allows you to use parentheses and respects the hierarchy of expressions, the result is displayed on the second line of the display with the ability to update or correct any character when there is an error in the expression.
