**From Ver.2.03, up to four layers of nested functions are supported. A calculation like √(log(exp(sin1.5))) is possible.
1. The following functions are inserted like as ordinary formula, then enter "=".
log、ln、exp、sin、cos、tan、asin、acos、atan、sinh、cosh、tanh
Example: log5.3 cos(√3) √(exp2+ln3)
2. The following functions are inserted as stated on the buttons.
rad(°): degree to radian, deg(rad): radian to degree
Example: rad50 deg0.87 ( or rad(50) deg(0.87) )
Enter sin(rad50) if it"s used in a trigonometric function
3. The following functions are inserted as each specific formula, then enter each function button.
1/x: After entering x number, tap "1/x".
Σ: Sigma (summation). Enter "start number:end number:formula with k"
Example: 1:10:k^3 = 1^3+2^3+3^3+4^3+.....+10^3
n!: Factorial. 5! means 1×2×3×4×5. After entering n number, tap "n!".
nPr: Permutation. Enter "n:r"
nCr: Combination. Enter "n:r"
4. "5%", "+5%" and "-5%" are sales tax calculation. Although default figure is 5%, you can change it by setting "Tax" on preference view.
In sales tax calculation, although the result is shown on Multi window and Answer window, the formula on Formula window doesn't change. Therefore, you can calculate multiple results without re-entering the formula.
Example: Sales tax for $10 item ( in case of 9.5% sales tax)
Enter 10 and tap "9.5%" -> (10)×0.095 = 0.95
Example: Tax-add price for $10 item ( in case of 9.5% sales tax)
Enter 10 and tap "+9.5%" -> (10)+0.95 = 10.95
Example: Before-tax price for $10(included tax) item ( in case of 9.5% sales tax)
Enter 10 and tap "-9.5%" -> (10)-0.86 = 9.14
5. Window size change
Before Ver.2, for changing window size, you have to use the slider in preference view. From Ver. 2, you can resize the window by swiping it.
First, tap the right half of Answer window and memory copy buttons are shown. During these buttons are shown, the windows are scalable.
When the Vertical window is displayed, you can swipe the window to the left or right. For Horizontal window, swipe to up or down.
If you double tap on the window, you can exchange between Vertical and Horizontal window.
5. Button swap
The number, operator and function buttons are transferable except "Next (Prev)" button.
To do this, use "Swap" button. You can find this button if you tap "Next" on the right side keypad.
Tap "Swap" button and select two buttons as following the message. You can select the buttons by swiping the keypad and changing page by "Next (Prev)".
Since the location of swapped buttons are saved, it is loaded on next execution. Also, if you want to select from different button setting, you can save by creating a new "Preference File" in preference mode. If you create Preference File, you can change settings by tapping "Select" button which is next to "Swap" button.
