Question about Casio MS-80TV Scientific Calculator

When the answer should be 1.34, it automatically rounds up to single decimal digit and shows 1.4. How do I make it stop rounding up?

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.

You must drop all the digits after the decimal mark (,). But first check the digit just after the decimal mark.

If that digit is 0,1,2,3,4 remove all the decimal digits.

If that digit is 5,6,7,8, or 9, you must increase by 1 the digit in the units position.

Examples

78.4.. rounds down to 78

78.5.. rounds up to 79

If that digit is 0,1,2,3,4 remove all the decimal digits.

If that digit is 5,6,7,8, or 9, you must increase by 1 the digit in the units position.

Examples

78.4.. rounds down to 78

78.5.. rounds up to 79

Two alternatives:

Press SHIFT MODE 6 then a digit greater than 2 to specify the desired number of digits to the right of the decimal point. For example, of you select 3 the number will be displayed rounded off to 0.004 .

Press SHIFT MODE 9 2 to select the NORM2 mode.

Be aware that in any mode if the magnitude of the number drops below 10^-9 then the calculator will automatically switch to scientific mode. The calculator can't display more than nine digits after the decimal point---the display just isn't big enough.

The number of decimal digits in your display is fixed to 0, so that all decimals are wiped out.

To correct,

Press the MODE button.

On the second line you have FLOAT 0 1 2 3 4 5 6 7 8 9

Move cursor to that line then use right or left arrow to highlight Float or 1 2 3 ..**Make sur that the number 0 is not highlighted. **

Change the display mode. Press SHIFT MODE 6 then the number of desired digits after the decimal point. Alternatively, press SHIFT MODE 8 and select one of the "Norm" modes.

This is all in the "Specifying the Number of Display Digits" section on page E-8 of the manual.

I don't think the calculator has that function, but what you can do is round on your own. If the decimal .005 or greater, you'd round it up to .01. Simple as that!

Hope this helped.

Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]

2. Hold [SET/%] key for about 2 seconds

3. Press [TAX+]

4. Input the tax rate

5. Press [SET/%]

Printing models (except HR-8TE):

1. Have calculator in "print" mode

2. Press [CA]

3. Hold [SET/%] key for about 3 seconds

4. Input the tax rate

5. Press [TAX+]

6. Press [SET/%]

^Top

Enter only the numerals, not the letters.

The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here

The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].

The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.

The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.

^Top

This switch is used to determine how many decimal places your answer is displayed in.

ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.

This is a markup on price procedure. The formula is as follows:

Markup%=(Markup Price-Cost)/(Markup Price)

Make sure that you are following the correct procedure.

Adding 10%: 200 [×] 10 [%] [+]

Subtract 10%: 200 [×] 10 [%] [-]

AP Calculus requires a graphing calculator.

Any graphing or scientific calculator is permitted on the following as long as it does not have a QWERTY keyboard, electronic writing pad or a pen-input/stylus-driven interface:

PSAT/NMSQT, SAT I

SAT II Math, IC & IIC

AP Statistics (graphing expected)

AP Chemistry

AP Physics

Cheer up, the calculator can display UP to 10 digits, no more. Internal memory keeps 12 digits. So clearly, this calculator is not fit to handle the precision you apparently are seeking. It may be time to look for a more capable calculator.

You have the calculator set to round everything in the display to zero digits after the decimal point. To change this, press SHIFT [DISP] and then a digit representing the number of digits you want to the right of the decimal point.

PRINT KEY:
To save paper you can only print what is displayed, even
in non-print mode.
Pressing after the entry of a number will print the entry
with the symbol “#” even in non-print mode.
Pressing will insert a separator into a number entry
such as a code, date, etc. Separators are displayed as a
period and dashes but printed as periods.
MEMORY + KEY / PRINT ON / OFF KEY:
Pressing selects print mode or non-print mode.
Cause the calculator to operate in a display / print or
display only mode, depending upon the calculator’s
present state.
“P” on the display: Print mode.
“NP” on the display: Non-print mode.
MEMORY – KEY / DECIMAL SELECTION KEY:
Pressing sets the number of decimal places in
the result.
“F” on the display:
The answer is displayed in the floating decimal system.
“3, 2, 1, 0” on the display:
Presets the number of decimal places in the answer.
“A” on the display (Add mode):
The decimal point in addition and subtraction entries is
automatically positioned to the 2nd digit from the lowest
digit of entry number. Use of the add mode permits
addition and subtraction of numbers without entry of
the decimal point. Use of , and will
automatically override the add mode and decimally
correct answers will be printed.

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.
