Scroll through numbers to review (and edit) your entries and calculation results. Share or transfer your results by emailing the stack.The Scrolling Scientific Calculator gives you fast access to both basic and scientific operations with large buttons in both portrait and landscape orientations. ** Featured in Utilities on 121 iTunes stores **Video demonstration available from the support link.* Adding machine: What is the most common use for a calculator? Adding numbers, of course! Just enter the numbers, review them by scrolling, with a swipe of your finger, then hit the [total] button. No more entering numbers twice to check your calculation.* Average and standard deviation: Enter the numbers, review them by scrolling, with a swipe of your finger, then hit the [stats] button. The total, count, average (mean), median, mode, variance, and standard deviation are added to the stack (and labelled)!* No awkward 80's style retro interface or tiny buttons: Scroll through panels of large operation buttons by swiping left and right.* Tap-to-recall to edit or use in calculations.- Tap any stack value to recall it to the text-entry box. Then i) use it in a calculation by tapping an operation such as [+], [%], etc or ii) edit it, then tap [Enter] to replace the originally tapped value.* Operations include: total, count, mean, median, mode, variance, standard deviation (population & sample), trigonometric, hyperbolic, logarithmic, powers, roots, inverse, factorial, percent, add, subtract, multiply, divide, etc.* Value formatting: Specify either the number of significant digits, or number of fraction digits after the decimal point. International number formats with group separator.* Display numbers as hexadecimal by simply scrolling to the hexadecimal panel.* Reverse Polish notation (RPN) operation.* iOS 4 - supports fast app switching and the Retina display.The Scrolling Scientific Calculator is ideal for:* Anyone who adds numbers together (e.g. receipt values.)* Anyone recording sample readings to find averages, variances and standard deviations.* Anyone who wants a scientific RPN calculator, and is looking for a modern, uncluttered interface ideal for their iPhone, iPod Touch or iPad.* Kids (!) learning to add and subtract love entering the numbers and seeing them on the screen before they hit the + or - operation buttons. They can talk through the operation as it happens.Note: This is an RPN calculator, so there is no "=" button. Proposed in the 1950s by Australian philosopher Charles L Hamblin, RPN is the way most people would actually calculate an expression in their head or on paper: "1 enter 2 enter +" instead of "1 + 2 =".
