Numerari Scientific Calculator

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

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

Numerari is made for a touch world---copy results from its history display to use in a new calculation with just one tap. Drag and drop to set user-defined keys.

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 axes limits

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

ADVANCED FUNCTIONS
● Popup keypad with 48 advanced functions
● Includes permutation, combination, factorial, double factorial, gamma, log gamma, digamma, log with any base, Riemann zeta, and error functions
● Includes all of the trigonometric and hyperbolic functions and their inverses
● 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

DISPLAY
● Scrollable build and history displays let you enter calculations of arbitrary size
● 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.
● Archive or email history images with different background and alignment options
