### How to round 6.45734 to the nearest hundredth.

You don't need a calculator for that.
- A hundredth is 2 decimal places, so your number looks like
6.45 734
Add the 3rd digit to the right of the decimal to itself. You'll get
6.46 434
Ignore the digits except for two decimal places, you get
6.46
Ta Da!

### HP 12 C display does not show entire numbers. How do I fix?

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.

### Answer only carries out to 4 decimal places

Press the MODE button until the screen shows: [Fix Sci Norm] for the display mode, then press the number corresponding to Norm (ie 3 for Normal) then either 1 or 2. Display mode Norm1 shows numbers that are less than 1 in scientific mode, whereas mode Norm2 retains decimal format where is fits on the display.

### I want to set the decimal place without using the decimal key--example: hit the 1234 keys and the shows \$12.34

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.

### HP12c seems to not have enough room for numbers BEFORE the decimal point. I try to enter the number "85" and all that will show up is the 8.000000000

Initial Setup

One adjustment is important before we get started. By default the 12C displays only two decimal places. This is not enough. Personally, I like to see five decimal places, but you may prefer some other number. To change the display, press "F" and then the number of decimal places you wish to display. I would press "F 5 " to display 5 decimal places. That's it, the calculator is ready to go.
You need to hold the "F" key.---------

1. Press and release the gold PREFIX key (f).
2. Press the number key for the desired number of decimal places (0 through 9).

### What is the default setting for the f cut 5/4 and the 4320 add 2 I don't know what to have these options set at thanks EW Seattle

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)
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.

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.
