I don't know which particular calculator model you have, but for an HP-12C, the manual says the following:

**Digit Separators **

As a number is keyed in, each group of three digits to the left of the decimal point is automatically separated in the display. When the calculator is first turned on after coming from the factory - or after Continuous Memory is reset - the decimal point in displayed numbers is a dot, and the separator between each group of three digits is a comma. If you wish, you can set the calculator to display

a comma for the decimal point and a dot for the three-digit separator. To do so, turn the calculator off, then press and hold down the [.] key while you press [ON]. Doing so again sets the calculator to use the original digit separators in the display.

From the manual PDF http://www.yorku.ca/ntahani/ADMS3530/EL738_OM.pdf

(page 8 and 9)

decimal places:

set up - 0 - 0 - (tab) displays DIG(0-9) select a number from 0 to 9 decimal places

significant digit:

setup - 0 - 0 - (SCI) displays SIG(0-9) again select a number from 0 to 9 to set...0 sets a 10 digit display

the floating point FLO_A and FLO_B is a nice little chart so i'd advise downloading the PDF if you need to set those :)

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.

"Fix" indicates the calculator is rounding results. Press "Fix" followed by "." (decimal point) to remove the fixed decimal setting.

I am not quite sure I understand but here is how to configure your calculator to display decimal results all the time.

Use LineIO

To set LineIO

In case you need to revert to the MthIO here is how to do it.

To set MthIO

If you want the advantages of MthIO but the results in decimal, you can do it as follows

Use LineIO

To set LineIO

- Press [SHIFT][MODE] to access (Setup)
- Select [2:LineIO]

In case you need to revert to the MthIO here is how to do it.

To set MthIO

- Press [SHIFT][MODE] to access (Setup)
- Select [1:MthIO]

If you want the advantages of MthIO but the results in decimal, you can do it as follows

- Press the [S<=>D] key after a result is displayed to toggle between decimals and fractions/radicals.
- Alternatively, pressing [SHIFT][=] will always display the results in decimals.

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.

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.

To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal

1) Press the "SHIFT" button

2) Press the "MODE/SETUP" button

3) Press the "2" button

This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps
