Dear Anita,
Here is how that works.
A decimal point goes just to the right of the number indicating the amount of dollars you have.
For example, if you have 10 dollars, the decimal point goes to the right, like this: 10.
After that decimal point you put the numbers telling how much cents you have.
If you have 15 cents, it will look like 10.15
I hope this helps you.
God bless your efforts.

You need to be in add mode, and have 2 decimal places selected for the result.
To change to add mode, make sure the 'K . A' switch is in the 'A' position. To get 2 decimal places in the answer, move the selector in the 'F 6 3 2 1 0' switch to the '2' position.
You can see the above described at
this Sharp.com page which shows the users manual. The manual shows examples.
SOURCE: SETTING UP THE DECIMAL ON NEW 210 TM
Set the +43210F switch to + (or 2).
On some models it is A43210F, then use A (or 2).
+ mode will let you enter numbers (monetary) without the decimal point and assumes cents; 2 mode will just round to 2 decimals, but you must enter the decimal.

Do you mean four places behind the decimal point? Page 21 describes setting for fixed decimal point 0 thru 9 places to the right.
