Calculator SC vs Codex Calc

The SC-323PU is a multi functional calculator. It is designed in a way, that it simulates the visual and operational aspects of a true pocket calculator, such that the user will be immediately familiar with its interface. A complete operation manual is included within the App. The SC-323PU offers the following calculator modes for different tasks: - SCIENTIFIC CALCULATOR - UNIT CONVERTER and UNIT CALCULATOR - LOGIC CALCULATOR (n-base conversion) • Full operating instructions are included in the App (visible when device is in landscape orientation). • All modes share the same memory contents, and calculation value, so that the different calculator modes can be used in one calculation task. • Pasteboard support (copy and paste) • Algebraic logic for calculation entry. • Priority of calculations according to a given mathematical formula. • 30 levels of parentheses or pending operations. • Variables and memories to store values and use in calculations. • Floating decimal point calculations with 20 digits mantissa and 2 digits exponent. • Calculations: Four arithmetic calculations, constant calculation, memory calculations, trigonometric and inverse trigonometric functions, hyperbolic and inverse hyperbolic functions, conversion of angles and time, reciprocals, square roots and cubic roots, X-th roots of Y, squares and powers, logarithmic and exponential functions, factorials, permutations, combinations, conversions of coordinates. • AER (Algebraic Expression Reserve) for repetitive calculations of expressions and formulas. • Complex number calculations. • Different display modes selectable: floating point decimal, fixed point decimal, scientific notation and engineering notation. • DEG/RAD/GRAD selector key. • Fraction calculations. • Time calculations. • Frame rate calculations. • 47 physical constants. • Unit converter and currency converter. • Calculations with mixed units. • The calculator is shipped with 84 physical units and 16 SI prefixes predefined. • Exchange rate of currency units will be updated automatically from internet. • Additional units can be defined by user. • Single and two lines view modes optimized for different conversion tasks. • Conversions between 4 base systems HEX, DEC, OCT, BIN. • Boolean operations AND, OR, XOR, NOT, bit shift operations. • Conversion from “little endian” to “big endian” format and vice versa. • Handling of 8, 16, 32 and 64 bit signed and unsigned numbers including overflow calculations. Also on your Apple Watch! You can do basic calculations, tip calculations, unit and currency conversions and even scientific calculations directly on your wrist. Designed with large keys for best usability on the small screen.

Codex Calc is the calculator for the rest of us: easy and intuitive, without sacrificing power and capabilities. Calculator • Unit Converter • Tip Calculator • RPN Mode • Full Scientific • History Tape All the power you need, wrapped in a beautifully designed interface that's simple without being simplistic. ADAPTS TO YOU Do you like big buttons, or small? Like minimalist interfaces, or are you a fan of bright and flashy? Prefer small fonts to see more detail, or big text and easy to read buttons? Codex Calc adapts itself to the way *you* like to work. FEATURES Everything you'd expect, plus: • History tape records all entries and calculations • Full suite of standard and scientific calculator functions • Unit conversion mode for forward and reverse conversions • Full tip calculator mode - taxes, tip, per-person amounts • RPN mode fully integrated • Rotation lock and sound on/off toggles • Seven different professionally designed visual themes • Multi-number memory and full set of memory-store operators • Full control over history tape font size • Single and multiple-line history tape formats • Large and small button sizes • Settings for customization (number formatting, behavior of clear key, display of calculation details, much more) Calculations: • Trig functions in degrees and radians • Log and power/exponentials • Scientific notation / exponent mode • Rounding and truncating • Random number generation • Parenthesis and sub-expressions ...and more! INTUITIVE TOUCH INTERFACE Take full advantage of your device's capabilities: • Overlays - rather than making buttons smaller to fit more, Codex Calc uses intuitive overlays on the existing buttons. • Popup Menus - hidden until you need them, pop-up context menus give you more power when the default action isn't quite what you need. • Zoomable History Tape - Tap the history tape to expand for more detail, change the font size, copy contents to clipboard, or forward as an email. View as single-lines to save space, or use multi-line view for more detail. • Multiple Flexible Layouts - Portrait and landscape, large and small buttons, and seven different graphical themes. • Easy-Touch Everything - Codex Calc's entire design approach revolves around "touch to activate." Tap the tape to see it bigger, swipe to scroll, long-press a button for more options, tap the display to copy or paste, etc.
