A great scientific calculator that works on iPad, iPhone and iTouch, so you get many Apps in one package! Swipe right or left with your finger to change between function groups on the iPhone and iTouch. This allows you to get the functions that are being used without rotating the device or using cumbersome "2nd" function keys. The iPad shows all the functions and rotates. The number display may be set to Scientific, Engineering, Fixed or Default for showing values and different number of decimal digits.
There are a total of 18 backgrounds to choose from, with varied colors and patterns.
This elegant looking calculator works on all iOS devices. It´s fully international in representing numbers as the user prefers with his country settings, so the period button becomes a comma in Europe. The calculations are done in extended accuracy so that the square root of 2 repeated a few times, followed by a square will result in 2, not 2.00000001 (try this on other calculators).
A low audible sound confirms your pressing of a button, which may easily be disabled by touching the speaker icon or turning off on the Info sheet. Last calculation can likewise be repeated by pressing the equal sign, and there are visible and audible warnings when an attempt is made to divide by zero or take the square root of a negative number. Memory is saved between uses. Degrees and Radians can be switched by pressing the symbol on the screen or a button.
The calculator shows local numericals depending on your Region Formats, Settings, i.e. in arabic ١٢٣.
