SOURCE: MS-80TV AUTOMATICALLY ROUNDS UP TO 1 DECIMAL DIGIT

The [MODE] key can be used to select the modes described below.

Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes

Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetric calculations

(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

SD: Single-variable statistical calculations

(sample standard deviation, etc.)

LR or REG: Paired-variable statistical calculations

(linear regression statistical calculations, etc.)

BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations

MAT: Matrix calculations (determinants, etc.)

VCT: Vector calculations

EQU: nth degree equations, simultaneous equations

2) Display Settings

Use these settings to control how calculation results are displayed.

Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

3) Angle Unit Setting

(90°=?/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads

4) Engineering Mode

Use this mode when you want to input and perform calculations using engineering symbols.

Increase the number of decimal digits in display.

- Press [SHIFT][MODE] to access the {SETUP)
- Enter the number (6) corresponding to option [6:FIX]
- In screen that is displyaed, enter the number of decimal digits you want (2, 3, or 4). If you enter 0, all decimal numbers will be displayed as integers (rounded). If you enter 9, you will have long numbers but that is hardly ever necessary.

SOURCE: all of my answers show up rounded to the nearest

- Press [MODE].
- Highlight Normal, it is not highlighted already, and press [ENTER].
- Use DownArrow to move cursor to the second line.
- If you want to keep all possible decimals digits highlight float and press [ENTER], then press [2nd][MODE] (QUIT) to exit configuration screen.
- f you want a limited number of decimal digits (2,3, 4 or 5), highlight the corresponding number on 2nd line an press [ENTER], then [2nd][QUIT] to exit configuration screen.

SOURCE: I have Casio fx-83ES. I'm using it in Mode 2 -

You can configure it as you wish. Press [SHIFT][MODE] to access the (SETUP) configuration screen, then select [8:Norm].

You will be prompted to choose Norm1 or Norm2. To help you find out which is more appropriate to meet your concerns, I am inserting a screen capture from the manual.

SOURCE: I have a problem with

Press the [SET UP] key, followed by the 0 key to bring up the display menu. You can select "FIX" followed by the number of digits to the right of the decimal point, or press cursor-down and select one of the NORM modes. Press [ON/C] to exit the menu.

Be aware that some numbers cannot be displayed exactly. For example, 1/3 is a 0.3 followed by an infinite number of 3s.

You haven't made the purpose of the question very clear Miriam so I am only guessing that it is an exercise in rounding or shortening decimal fractions to make them easier to work with which is often convenient when approximations do not matter.

The general rule of rounding is to take the last figure and if it is less than 5 it is erased and if it is 5 or more it is erased but 1 is added to the next or the new last figure and the process is repeated until the fraction is shortened to the required length.

If you take the decimal fraction 0.8745, after the first stage of rounding it would become 0.875 and then after the second stage of rounding it would become 0.88 and then finally rounding to one decimal place the result would be 0.9.

I hope this helps you deal with your fraction. I apologise in advance if I have misunderstood the question.

You first have to decide what accuracy, that is how many decimals, are needed in the answer. There is a rule of thumb which says you should not quote more decimals than the accuracy of the data used in the calculation. Money calcs of course would usually use just 2 decimals.

So when dropping decimals round up the last remaining of the dropped decimal is 5 or over, otherwise it is unaltered. So 2.2361 rounded off to 3 dec is 2.236, and rounded to 2 dec it is 2.24.

Up Arrow: Answer is rounded up

5/4 key: Answer is rounded off

Down arrow: Answer is rounded down

The decimal will float if the calculation is multiplication or division

If the decimal selector is set to F then the answer is always rounded down

5/4 key: Answer is rounded off

Down arrow: Answer is rounded down

The decimal will float if the calculation is multiplication or division

If the decimal selector is set to F then the answer is always rounded down

There are no decimal digits in this number. You can put a decimal mark in 8 537 000. and append two zeros, or more.** But I would not call that rounding** 8 537 000.00

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).

There are several different rounding schemes, but by the most common it would be 57.50 and 58.49 .

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.

• 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.

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.

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