Adding 0


What does that mean adding? Displaying extra zeros? If that is the case Press [2nd][.] and limit the number of decimal you want.
You can put the calculator in FLOating mode: Press 2nd DRG and choose FLO.

I don't know if maybe my calculator has a function turned on that rounds the answer to a whole number? But here is an example: 106 x 6.32 = 670 according to my calculator, which is wrong. The real answer...


Your calculator is set to display no digits after the decimal point. To change this, you have two options: press 2nd [SCI/ENG] then select "FLO" for floating decimal or press 2nd [FIX] then select the desired number of digits after the decimal point (or F for floating).

Cant get "fix" off calculator


This is indicating that the calculator is set to a fixed decimal notation. You can change the notation to scientific or engineering, but in those cases you'll see either "SCI" or "ENG" on the display in place of the "FIX".

You can also specify a floating notation by pressing 2nd [FLO], in which case none of the annunciators light up.

How do you get percentages and fractions?


To calculate using fractions you should use the [A B/C] button located on the 3rd row 2nd column of the keypad. For example, if you want to calculate 3 1/2 + 3/4, you should input 3 [A B/C] 1 [A B/C] 2 [A B/C] [+] 3 [A B/C] 4 [A B/C] [ENTER]. You should get an answer of 4 1/4. To convert that into percentages or decimals press the [2nd] button first then the [FD] button which is the [PRB] button. For example to make 4 1/4 to appear as 4.25 you press [2nd] then [PRB] ([FD]) then [ENTER]. If you want it into a percentage, multiple the decimal value by 100.
