Scientific Calc vs Command

Scientific Calculator for iPad and iPhone. Easy to access the scientific functions by swiping between exponents, logs and sinus functions so all buttons are large and uncluttereds, this allows you to work faster and more reliable (no rotation or "2nd" function keys needed). All the functions are visible on the iPad, but more are revealed by rotating to landscape. Balloon help for easy functionality. Features: - Correct with a backspace key if you enter a wrong digit without having to redo. - Parantheses and correct calculation priority. - Copy and Paste numbers to other Apps, by tapping on the display. - Change number display to Fixed, Scientific, etc., by tapping on the display. - Customize you background and fixed digits. - An audible sound confirms if you have pressed a button, which can be easily disabled by touching the speaker. - Previous calculation is repeated when the equal sign is pressed. - Memory is saved between uses. - Degrees and Radians can be switched by pressing the symbol on the screen or a button. - A visible and audible error when trying to divide by zero or take the square root of a negative number. - Numbers are shown in local format, depending on your Region Formats, i.e. comma used in Europe. - Calculations are done in extended accuracy so that the square root of 2 repeated a few times, followed by a square will result in 2, not 1.999999999999983.

Command-Line Calculator (CLCalculator) provides the most fluid interface, especially if you are performing chained calculations i.e. multiple calculations that rely on the results of previous calculations. By providing a command-line interface, CLCalculator allows you to easily enter and view the history of your calculations. You focus on your calculations instead of being intimidated by myriad of buttons on a traditional calculator interface! In addition to performing basic calculations, CLCalculator provides an array of features such as: - Assign and reuse variables - Complex numbers - Number bases i.e. binary, octal, hexadecimal - Constants e.g. e, pi - String manipulation - Matrices - Unit conversion: in-built and user-defined (create your own units!) - Functions: in-built and user-defined (create your own functions!) - Arithmetic functions e.g. fraction, square root, rounding off, ceiling, floor, logarithm - Algebra functions e.g. derivative, simplify symbolic expressions, solve linear equations - Bitwise functions e.g. bitwise and, not, or, left and right shift - Combinatorics functions e.g. Bell, Catalan, Stirling numbers - Geometry functions - Logical functions e.g. and, not, or, xor - Probability functions e.g. combinations, permutations, factorial - Relational functions - Set functions e.g. cartesian product, intersection, union - Statistics functions e.g. mean, median, mode, standard deviation, variance - Trigonometry functions e.g. sin, cos, tan, cot, sinh, acos - and much more! The app also comes with a comprehensive in-built help system with plenty of examples. CLCalculator is powered by math.js (https://mathjs.org/)
