Publisher Description
Perpenso Calc is five calculators in one fully paid app: scientific, statistics, business, hex and bill/tip. All five modes are included, there are no longer any optional modes. Perpenso Calc 4 is a related lite app with optional modes. Perpenso Calc is offered at a discounted price and may cost less than adding all your desired functionality to Perpenso Calc 4. Perpenso Calc includes: A calculator tape A built-in manual Nine color schemes All calculators offers: Copy and paste Optional RPN entry Decimal based arithmetic (no binary rounding) 20 digit precision (enough for 64-bit arithmetic) 10 memory registers Customizable display lines (iPad only) Scientific mode provides: 72 operations (43 complex number) Fractions Complex numbers, cartesian and polar 2D rotation Scientific and engineering notation Unit and time conversions Statistics mode includes: 42 operations Optional worksheet for data entry/editing and viewing common stats Importing data from the web Single and two variable data Swap XY data Mean, weighted mean, geometric mean, median and mode Z-score Standard deviations Covariance and correlation Percentile Sums Linear regression including slope, y-intercept, predicted x/y, SSE and SSR Combinations Permutations Geometric, hypergeometric, poisson and binomial probability functions Business mode offers: 53 operations Optional worksheets for data entry/editing and performing common calculations Breakeven point Profit margin Time value of money Amortization Cash flows Interest rate conversion Running total Hex mode provides: 43 operations Optional worksheets for data entry/editing and performing common conversions Decimal, hex, octal and binary 64-bit and 32-bit modes Unsigned and signed modes Bitwise operators Byte swapping UTF-8, UTF-16 and UTF-32 encoding, decoding and conversions IEEE single and double precision floating point encoding and decoding Dotted quad encoding RGBA decoding with a preview of the color Bill mode allows you to: Add items to a scrollable list Set item quantity Set the percentage of an item that you are responsible for Set tax and tip percentage Set tax and tip amount Split the total Send itemized bill to calculator tape Enter/edit items and view some calculations on an optional worksheet Efficient and explicit calculations. RPN is an optional entry method that gives you explicit control over calculations without using parenthesis. RPN is a favorite of many handheld calculator users. 20 digit precision, enough for 64-bit arithmetic. Many calculator apps use the hardware floating point unit (FPU) and are limited to around 16 decimal digits of precision, far fewer than the 20 needed to perform 64-bit arithmetic. Perpenso Calc is always using 20 digits of precision internally. Decimal arithmetic, no binary rounding. Can other calculator apps calculate 0.5 0.4 0.1 = 0? Surprisingly many cannot and display a very small number rather than zero. The FPU performs binary arithmetic and as numbers are converted between binary and decimal small rounding errors can occur. Handheld calculators use decimal arithmetic, not binary, to avoid such rounding errors. So does Perpenso Calc. Seamless support for fractions. In Perpenso Calc fractions are generally interchangeable with decimal numbers. Nearly all calculations accept fractions and will return a fraction when the operands are fractions. Fractions may be displayed as, and converted between, proper and improper forms. Better support for complex numbers than many handheld calculators. Most mathematical operations in Perpenso Calc accept complex numbers, more operations than many handheld calculators. Complex numbers may be displayed as, and converted between, cartesian and polar forms.
Requires iOS 4.3 or later. Compatible with iPhone, iPad, and iPod touch.
