Numerari Scientific Calculator

Numerari's comprehensive unit calculations, easy-to-use complex numbers, powerful graphing, and advanced functions make it the perfect tool for solving challenging science, engineering, and mathematical problems.

● Routinely use units in your calculations to verify unit consistency and convert units for any physical quantity. ● Enter calculations with mixtures of rectangular and polar complex numbers and easily convert answers between forms. ● Graph multiple functions on rectangular or polar grids using linear-linear, linear-log, log-linear, log-log, linear-decibel, or log-decibel scales. ● Trigonometric, hyperbolic, permutation, combination, Bessel, gamma, factorial, etc. keys cover a wide range of applications.

EASY-TO-USE INTERFACE ● Copy from the history display to the build display with just one tap---copy the entire previous expression, copy a number with its units, etc. ● Scrollable build and history displays let you enter calculations of arbitrary size ● Drag and drop to set user-defined keys

UNITS AND CONSTANTS ● Popup unit keypads with 96 units ● Combine units with multiplication, division, and power operations ● Conversions for any physical quantity can be made by combining units ● Includes all metric (SI) units, many related units, and 18 metric power prefixes ● Includes 48 of the most common English units ● Checks calculations for unit consistency ● Can suggest units for the answer, but you can also specify the answer units---answer units are checked for consistency and any required unit conversions are done automatically ● Popup constant keypad with 48 physical and mathematical constants ● Constants cover the full range of areas from basic physics and chemistry to electromagnetics and quantum mechanics

COMPLEX NUMBERS ● Enter any mixture of rectangular or polar complex numbers in a calculation ● Complex numbers can have units ● One tap switches between rectangular and polar as the default answer form ● One tap switches between radians and degrees as the default polar argument units ● If the last answer was in rectangular form, one tap shows it in polar form and vice versa

GRAPHING ● Graph functions on rectangular and polar grids ● Five scales are available for labeling axes: regular linear (default), pi linear (axis is labeled in multiples of pi), regular logarithmic, and two special logarithmic decibel scales ● Graph multiple functions and give each line a unique color ● The history display saves your graph specification and a thumbnail image of the graph so that you can reopen the graph to full screen with just a tap. You can create similar graphs by copying old ones. ● Units are fully integrated---use units in your function expressions and on your axis limits

ADVANCED FUNCTIONS ● Popup keypad with 48 advanced functions ● Includes all the trigonometric and hyperbolic functions and their inverses ● Includes permutation, combination, factorial, double factorial, gamma, log gamma, digamma, log with any base, Riemann zeta, and error functions
● Supports differential equation applications with Bessel and Airy functions and Legendre, Laguerre, Chebyshev, and Hermite polynomials

KEYBOARD ● The option to switch between two ergonomic keyboard layouts lets you decide which is best for how you use your iPad ● 10 user-defined keys that you can assign with a simple drag and drop---save special constants, groups of units, and expressions ● UNDO/REDO the last 50 edits in the build display ● 17 color themes: cool, warm, outdoors, orchid, sweet, chocolate, steel, graphite, robust, khaki, pastel, subway tile, sapphire, turquoise, ruby, emerald, and neutral
