Tap the Info Icon to display application information.
Tap the Memory Icon (only displayed if values in memory) to display the values in memory. Select a memory to use the value in the current calculation.
Tap the Variables Icon to display the variables. Select a variable to use the value in the current calculation.
The memory button (M) will toggle several other buttons to Clear All Memories (MAC), Clear Memory (MC), Set Memory (MS), Recall Memory (MR), Add to Memory (M+), Subtract from Memory (M-), Multiply by Memory (Mx), Divide into Memory (M÷) and Swap with Memory (x↔m).
After selecting the Memory button (M) you can optionally select an alternative memory location from 1 to 9 (0 is the default location).
The decimal point button (.) will toggle to the exponent button (E) once a decimal point has been entered.
The Inverse button (inv) toggles all trigonometric buttons (sin, cos, tan ,csc, sec, cot) to their respective inverse function, e.g. Sine (sin) becomes Arcsine (sin-1).
The Hyperbolic button (hyp) toggles all trigonometric buttons to their respective hyperbolic function, e.g. Sine (sin) becomes Hyperbolic Sine (sinh).
Inverse and Hyperbolic buttons can be combined.
The Degrees, Minutes and Seconds button (° ' ") toggles the display bewteen a decimal number and an angle represented in degrees, minutes and seconds, e.g. 45.56 is displayed as 45°33'36". This button is also used when entering an angle e.g. 45 degrees, 33 minutes and 36 seconds can be entered as: 4 5 (° ' ") 3 3 (° ' ") 3 6.
The Radians button (rad) toggles to Degrees (deg) and Degrees (deg) back to Radians (rad) The current angle mode is displayed at the top.
The Hexadecimal, Decimal and Binary buttons (hex, dec, bin) change the number base to 16, 10 and 2 respectively. Any base from 2 to 16 can be chosen with the Base button (basen) followed by the number 2 to 9 or letter A (10) to F (16).
The current base is displayed at the top. Base 16 displays as Hex, base 8 displays as Oct and base 2 displayes as Bin.
If any base other than Decimal is chosen, the current value will be truncated to an integer.
Non-Decimal numbers are only supported up to 64-bit values.
The Left Shift button (<<) and Right Shift button (>>) shift the current value by a single digit, e.g. 10 will Shift Left (<<) to 100 regardless of base.
Select the Record (rec) button to start recording a custom function. When promtped, select a button (P1 to P24) to store the function.
The Record button (rec) will toggle to Save (save) and the Edit (edit) button will toggle to Cancel (cancel) during the recording.
Most buttons can be used during the recording, including memory functions and variables.
If variables are used in a recorded calculation, they can optionally prompt for a new value when the calculation is performed but selecting the custom button.
Select the Edit (edit) button to display a list of all the programmable buttons. Seelct a button from the list to edit the button name, description, text color and background color.
In the screenshot, the programmable button P1 has been edited to change the name to "Area", the text color to orange and background color to purple.
