How do you change the number of default decimal place settings from 2 to 3? Thank you

Your BA II PLUS stores numeric values internally to an accuracy of 13 digits. However, the numbers it displays depends on the number of decimal places to which you have it set (choice of 0–9 or floating decimal). To set the number of decimal places displayed to three: hit [2ND][FORMAT][3][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.

Initial Setup

One adjustment is important before we get started. By default the 12C displays only two decimal places. This is not enough. Personally, I like to see five decimal places, but you may prefer some other number. To change the display, press **"F"** and then the number of decimal places you wish to display. I would press **"F 5 "** to display 5 decimal places. That's it, the calculator is ready to go.

You need to hold the "F" key.---------

The selector you are asking about is the "decimal selector". The result displayed/printed, will be in a format according to the position that you have selected as follows:

f = floating (the result will be in the number of decimal places that were entered on the keyboard

4= fixed 4 decimal places (x.0000)

3= fixed 3 decimal places (x.000)

2= fixed 2 decimal places (x.00)

0= fixed 0 decimal places (x)

add 2= (add mode*,fixed 2 places) ($.00)

Note* "ad mode" automatically enters the decimal place when entering the number on the keyboard. If you enter "123", the displayed ammount will be "1.23". If you enter "1", the display will read ".01". This is a useful setting when adding a list of numbers in a dollars/cents format, however, be careful, if entering a whole dollar ammount "three dollars" be sure to enter the decimal point, or enter the number as "300". If you don't, the result will be ".03", instead of the 3 dollars you intended.

Make sure that the decimal float option didn't get changed by mistake:

Press the MODE key, cursor down 1 selection to FLOAT, then cursor right to the decimal place that you need to be accurate to, then press enter. Typically, this is set on FLOAT by default.

By default the BAII Plus displays only two decimal places. This is not enough. Personally, I like to see five decimal places, but you may prefer some other number. To change the display, press the 2nd key, then the decimal point key, and, when prompted, enter the number of digits you would like to see displayed. You must then press the Enter key to lock in your choice. I would press 2nd, ., 5, Enter to display 5 decimal places. Now press 2nd, CPT to return to a blank screen. Problem solved.

One other adjustment is important. The BAII Plus comes from the factory set to assume monthly compounding. That's fine, I suppose, but its better to set it to assume annual compounding and then make manual adjustments when you enter numbers. Why? Well, the compounding assumption is hidden from view and in my experience people tend to forget to set it to the correct assumption. Of course, most people don't recognize a wrong answer when they get one, so they blithely forge ahead. To fix this problem press 2nd then I/Y and enter 1 when prompted. Now press Enter and then 2nd, CPT to return to a blank screen. Problem solved.

Tha calculator has two Input/Output modes: MthIO (also called Natural Display or TextBook display, the default mode) and LineIO the old way where eveything is on a single level line.

In MthIO expression appear as if you write them by hand or as in textbooks: multilevels, fractions are fractions, and roots are radicals. The results are also expressed as a mixture of fractions and radicals.

To set MthIO press [ŜHIFT][MODE] to access the (SETUP) options, thaen select [1:MthIO]

In lineIO, expressions arew typed in on a single level line, fractions are converted immediately to decimal numbers, and so are radicals.

Results are always decimal numbers (Scientific, Fixed, or Normal)

To set LineIO as the default IO mode, press [SHIFT][MODE] to access the (SETUP) options and select [2:LineIO].

If your default mode is set to MthIO, you can still force your result to be a decimal number by pressing not the [=] sign but [SHIFT][=].

If you have a string of calculations that you must to perform to get a single numerical result you can perform all calculations in MthIO, and just before calculating the last result press [SHIFT][=]. You result will be in decimal format.

You can convert any fraction/radical result into a decimal format by pressing the [S<=>D] key between the [ ) ] and the [M+] keys. You can also convert a decimal number into a fraction/radical format (not always because there are limitations to the number of total symbols that can be displayed on screen).

For you the simplest ways to have decimal results is to press the [S<=>D] key after result is displayed or the [SHIF][=] key sequence just before result is calculated.

Hi,

Press** MODE**. use arrow to highlight **NORMAL ** and press** ENTER**.

Then use down Arrow to go to second line and highlight a number between**1 and 9, **which will set the number of decimal digits to the one you entered. Alternatively, highlight **Float** to set the number of decimal digits to the default.

After you finish configuring, press**2nd QUIT t**o return to main calculator screen.

Hope it helps.

Thank you for rating this solution.

Hello,

It seems to me that you are omitting a step: see screen capture from manual (step 4). Hope it helps.

Hello,

Since you bent on deactivating the very features that make your calculator so versatile and so powerful, here it is.

Press [SHIFT][MODE][2:LineIO] and you will see no more fractions, nor radicals etc. You asked for it.

Hope it helps.

From the manual:

**SETTING THE NUMBER OF DECIMAL DIGITS**

Numbers of decimal digits of calculation results can be specified by pressing [C-CE] twice, then press [C-CE]and [M+] simultaneously.

The decimal digit assignment will appear as “F” (for “floating point”), “2” or “0” on the LCD. (The default is “F”.)

Press and hold [C-CE] and [M+] until the symbol changes.
