The Scrolling Scientific Calculator gives you fast access to both basic and scientific operations with large buttons in both portrait and landscape orientations.
* 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.
* Statistics: Enter the numbers, review them by scrolling, with a swipe of your finger, then hit the [stats] button. The following statistics are added to the stack and labelled:
Count,
Total,
Total Of Squares,
Product,
Maximum,
Minimum,
Range,
Mean,
Median,
Mode,
Root Mean Square,
Geometric Mean,
Variance,
Unbiased Sample Variance,
Population Standard Deviation,
Sample Standard Deviation.
* No awkward 80's style retro interface: Scroll through panels of large operation buttons by swiping left and right.
* 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.
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 =".
