Version History This update has settings menus and color themes that automatically adjust for the iOS dark mode. It also makes copying from the history to the build display faster. 1.5.3 09/23/2023 This update adds support for the latest OS versions and screen sizes. We also updated the constants to the most current CODATA recommended values. 1.5.2 07/26/2023 This is a minor update to add 64-bit support for iOS 11. We also updated the constants to the 2014 CODATA recommended values. Our major update is still on the way. 1.5.1 09/28/2017 (Note: Complex conjugate has moved to the advanced functions keypad.)

ADDED FUNCTION GRAPHING ON RECTANGULAR AND POLAR GRIDS
Now it is easy to graph functions using a forms-based interface in the build display---just tap the new "Graph" key to get started. You can specify a simple graph in seconds but there are a variety of options for more advanced applications.
● 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.
● You can mix scales to create linear-linear, linear-log, log-linear, log-log, linear-decibel, or log-decibel graphs.
● You can 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.
● Unit consistency is checked and unit conversions between multiple functions are done automatically.
● Polar graphs use a true polar grid so that you can easily see the relationship between radius and angle.
● You can select the colors for the background and grid.
See the "Graphing" and "Graphing with Decibels" sections in the help.

ADDED METRIC PREFIXES OPTION FOR ENGINEERING MODE NUMBER FORMATTING
Select the "Try to Use Metric Prefix" option in the settings for the engineering mode exponent and Numerari will try to use a metric prefix instead of an exponent when there are simple units. For example, it will return an answer like 91 mA automatically instead of 91x10^-3 A.

ADDED FOUR ADVANCED FUNCTIONS: ABSOLUTE VALUE (OR MODULUS), COMPLEX ARGUMENT, REAL PART, AND IMAGINARY PART
The advanced functions keypad was updated to add these functions which are particularly useful for graphing characteristics of complex number expressions. Note that the polynomials and Bessel functions now share keys using a new POLY/BESSEL switch

ADDED TIME AND ANGLE UNITS TO THE ENGLISH UNITS KEYPAD
If you work with English units, you no longer have to switch back to metric units to get seconds, minutes, radians, etc. These units now appear in the same places on both the metric and English unit keypads. Note that the English energy and radiation units take the place of some of the metric prefixes when using English units. The new volume unit "olympic swimming pool" was also added in the process.

ADDED "EMBEDDED CONVERSION" FOR UNITS
Now you can use the conversion operator inside of an expression. For example, this is useful for converting a temperature in Celsius to an absolute temperature scale, such as kelvin, in an expression that must have absolute temperature. You can also use embedded conversion inside of a graph form to specify the units that you want on a function you are graphing. See the "Constants and Units" and "Graphing" sections in the help. 1.5 02/03/2014 NEW KEYBOARD LAYOUT OPTION
Now you can choose between our original keyboard layout and a more traditional rectangular layout. No matter how you like to use your iPad, there is an efficient keyboard layout for you. Go to the "settings & tools" to choose.

ADDED 42 MORE ADVANCED FUNCTIONS
Our new advanced functions keypad adds 42 more functions for math, science, and engineering. These include the permutation and combination, factorial and double factorial, the gamma function, the log gamma function, the digamma function, the log with any base, the error functions, and the Riemann zeta function. For differential equation applications, the Bessel and Airy functions along with the Legendre, Laguerre, Chebyshev, and Hermite polynomials were included. An additional six trigonometric and six hyperbolic functions were added to give Numerari a complete set of 24 trigonometric and hyperbolic functions. The advanced function keypad is brought up by tapping the button that was formerly used to show the hyperbolic functions.

ADDED 36 MORE CONSTANTS
Our new constants keypad adds 36 more mathematical and physical constants (using the latest CODATA values). These include fundamental particle masses, magnetic moments, Compton wavelengths, molar volumes, Josephson constants, radiation constants, the fine structure constant, and many others. The original units and constants keypad has now been separated into a units keypad and the new constants keypad. This allowed us to add the additional constants while letting you see more of the history when either keypad is up.

Note: The precedences for the negative sign and postfix operators have been adjusted so that a negative number must be surrounded by parentheses to raise it to a power or apply a factorial. This matches the standard calculator and mathematical software convention instead of the spreadsheet convention. 1.4 04/29/2013 ARCHIVE HISTORY IMAGES FOR REFERENCE, DOCUMENTS, AND SHARING
There is a new "Archive History" feature in the settings & tools that allows you to generate images of your calculation history with a variety of options. You can crop your history by specifying how many of your calculations should be included. This makes it easy to send a friend your last few calculations. In addition to the normal calculator color, the image can have a white background for easy inclusion in documents or a transparent background for mixing with other graphics. In the image, you can specify left or right alignment of your calculations, you can turn dividing lines on or off, and you can even turn off the display of unit conversion specifications to give your calculations a more standard appearance. Images can be saved with screen captures (press the "home" and "sleep/wake" buttons at the same time) or emailed.

UNIT ENHANCEMENTS
The prediction of the answer units for expressions involving English and angular units has been improved, and a problem with prefixes in certain situations has been resolved. The "gon" unit has been replaced with the more common "rev" (revolution) unit. (If you use the "gon", you can save it to a user-defined key before you upgrade). 1.3 03/01/2013 NEW COLOR THEMES
Choose from seventeen different color themes: cool, warm, outdoors, orchid, sweet, chocolate, steel, graphite, robust, khaki, pastel, subway tile, sapphire, turquoise, ruby, emerald, and neutral. Spanning the range from vivid to muted colors, there is a theme to suit every user.

USES HIGH PRECISION VALUES FOR CALCULATED NUMBERS REGARDLESS OF FORMATTING
Even if a calculated number is rounded to show just a few digits in the history display, the full precision of the number is now preserved in the background in case you use that number in future calculations. You can also turn on a new option in the settings called "Color Calculated Numbers" to show calculated numbers in a different color wherever they are used to remind you that those numbers maintain their full precision. 1.2 01/29/2013 Now you can drag your finger on the keyboard to rapidly move the build display cursor left, right, up, or down through a calculation.

The build display has new touch bars that let you jump instantly to the extreme left or right of a calculation.

A new option, "Confirm History Deletes", is available in the settings. If you turn this switch on, you will be asked for confirmation whenever you try to delete a history entry. 1.1 12/15/2012 Fixed functionality of the CLR ALL key in iOS 6
