There is a switch above the numbers pad that allows you to select the number of decimal points. slide it over to the setting desired.

It is common for this setting to be unintentionally moved.

Good luck and don't forget to vote.

In the product details of this calculator, it states that there is a "decimal point selector." This is normally a slider starting with the letter F followed by the numbers 0123 etc. It is probably on 0. You can set the number of decimals to whatever you want, or use F for full numbers. For example, if you set this to 2, you should always get 2 decimals.

Good luck,

Paul

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.

### How to convert percent to fraction

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

- Divide the percent by 100 to get decimal number.
- Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
- Calculate the factor (f) for making the decimal number an integer:
*f*= 10*to power d*

Example:

*f*= 10 power 2 = 100

- Multiply and divide the decimal number x by the factor f:
*x***f*/*f*=*y*/*f*

Example:

2.56 * 100 / 100 = 256 / 100

- Find the greatest common divisor (gcd) of the fraction.
Example:

gcd(256,100) = 4

- Reduce the fraction by dividing the numerator and denominator by the gcd value:
Example:

256 / 100 = (256/4) / (100/4) = 64/25

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

step 1: divide decimal number by 8

step 2: write down the residual of division

step 3: if the result of division if 7 or less, write it to the left of residual you wrote in step 2, and there you go, you;ve got an octal represent. If the result is greater or equal to 8 then:

step 4: divide that result by 8

step 5: write the residual of that division to the left of the last one you wrote

step 6: from tis point everything is the same as from step 3.

Example: calculate octal represent of 123

123 / 8=15 , and residual is 3

15 >= 8, so the next thing you do is:

15 / 8 =1, and residual is 7

so far, we have 73

1<=7, so you write it to the left of 7, and there you go, 173 is octal represent of 123.

Hope this was helpful.

if you want to check your calculations, most calculator software has option to automatically calculate octal represents, i.e.

Hi,

You need to change the display format.

Press the [MODE] key a certain number of times until the screen displays Fix, Sci, Norm on one line, and 1 2 3 on the next line, with 1 under Fix, 2 under Sci and 3 under Norm.

Press 1 (Fix) followed by a number (1,2,3, etc.) This second number will set the number of decimal digits. In other words, if you press 1 (Fix) 3 all your results will have 3 decimal digits. If you choose 0, your results will not show decimals.

Hope it helps.

Thank you for rating the solution.

Hello,

To convert from fractions to decimals, and from decimals to fractions use the [S<-->D] key. If you want your decimal results to have a fixed number of decimal places press [SHIFT][SETUP][6:Fix]. Screen shows Fix 0~9. Enter the number of decimal places exemple 3.

Dans ce cas 1/6 is displayes ase 0.167.
