You round a number with several decimal places to a number with fewer decimal places.
1.14 rounded to 1 decimal place 1.1
What you are asking for can be done by putting a zero after 4 and write 1.140, BUT that is not rounding. In fact you can put as many zeros after 4 as you want.
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.
CUT: Values are cut off to the number of decimal places speicified by the current Decimal Place Selector setting
UP: Values are rounded up to the number of decimal places speicified by the current Decimal Place Selector setting
5/4: Values are rounded off (0,1,2,3,4 are cut off; 5,6,7,8,9 are
rounded up) to the number of decimal places speicified by the current
Decimal Place Selector setting
Above the feed button is an area for controlling the decimal placement. By leaving the slider on +, you have to manually put the decimal in.
0 - Means no decimal will be placed.
1 - Put it one place to the end. Ex: 4132.5
2 - Will make it read 413.25
3 - Will be 41.325
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][5][ENTER]This setting also continues indefinitely (even though the calculator is turned off and on) until it is changed.
I found this solution on the HP website. Turn it on, and do what it says. Then turn it off and back on again, and the extra decimal places should show.
