Show two decimal places

If you mean it is not showing everything after the decimal point, you can change that by pressing the [f] key followed by the number of decimal places to display. For example, to restrict it to 2 places, press [f][2]. If you want to see 4 places, press [f][4].

To show all possible decimal places, use the sequence [f][9].
From the manual (http://www.hp.com/ctg/Manual/c00363319.pdf):
"To display a different number of decimal places, press f followed by a digit key (0 through 9) specifying the number of decimal places. In the following examples, notice how the displayed form of the number inside the calculator - 14.87456320 - is rounded to the specified number of digits."


"Although nine decimal places were
specified after f, only eight are
displayed since the display can
show a total of only 10 digits. "
The standard display format, plus the specified number of decimal places, remain in effect until you change them; they are not reset each time the calculator is turned on. However, if Continuous Memory is reset, when the calculator is next turned on numbers will be displayed in the standard display format with two decimal places
shown.
If a calculated answer is either too small or too large to be displayed in the standard display format, the display format automatically switches to scientific notation. The display returns to the standard display format for all numbers that can be displayed in that format.

You can select the A (K . A) and then the # of decimal places (F 6 3 2 1 0) you want. So if you want to enter 1234 & it calculates 12.34, this will work.

Hold (C.CE) then whilst holding it press (M+) for approximately a second and it will move one place along in the three settings (F, 2 and 0) F shows full decimals, 2 shows 2 decimal places and 0 as yours is set to now round to the nearest whole number. I have just been sat at my desk trying to work this out as my calculator was too set to '0'. Took me reading the 'DEC DET' text with lines pointing at 'M+' and 'C.CE' to finally crack it!

Hope this helps.

Press 2ndF TAB and then a digit specifying the number of digits you want after the decimal point.

You need to set the number of decimal places to 1 or more.

• Press [2nd] [MODE] and scroll to FLOAT.
• Press the right arrow key until the number of decimal places needed is highlighted.
• Press the [ENTER] key.

For 2 decimal places, 2 should be highlighted. All answers will then be rounded to 2 decimal places.

• Press [2nd] [QUIT] to return to the home screen.

This is an easy one and happens often. Simply depress the orange "f" key and then select how many decimal points you want on the numeric keys. For example, for two decimal places you would push "f" 2. I usually keep mine on 3, but you can take it from here.

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.
