Text Calculator vs Pascal

This is a full text calculator. Just enter your formula in the text box and tap the '=' button (or 'Return' on the keyboard). It keeps a history of your calculations. This way you can check for typos and errors in your calculations. Features: - Just tap the result or formula in the history to reuse it. - Email the history for backup or further processing - You can use the Google calculator as well (e.g. for unit conversions). - Available functions: sin, cos, tan, asin, acos, atan, sqrt, exp, log, pow, abs, round, ceil, floor, random - Available constants: PI, E, LN2, LN10, LOG2E, LOG10E, SQRT2, SQRT1_2 - iPad split screen support - Support iPhone 6 and 6+

Pascal (formerly Calculator³) is a professional-grade 3-in-1 scientific, graphing and programmer calculator. Scientific Calculator¹ - Supports degree, radian and gradian modes - Decimal factorials - Modulo operator - Permutations (nPr) and combinations (nCr) - Standard memory functions - RPN mode Graphing Calculator² - Includes all functions the scientific calculator offers - TI-like design - Perform calculations on a smart tape (i.e. no need to close parenthesis, multiply out brackets, real-time syntax highlighting) - Plot graphs using adaptive sampling algorithm to generate precise results - Show or hide roots/intersections and trace values Programmer Calculator³ - Supports 8, 16, 32, and 64-bit bitwise calculations - Binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16) numeral systems too - Unicode (UTF-16) and ASCII character encoding - A binary table that shows you in real time the binary representation of the current operand - RPN mode
