I'm wrighting a programme and i want to round the final number. the programme calcs 'I', then i have written;

:round(1,5)->J

:Output(8,5,J

:Pause

when i run the programme, it works fine, except it diplays an answer that isn't rounded at all; usually it has about 9 decimal places.

what am i doing wrong???

When your writing your program there is a much easier way of doing it. Just where ever you want in your program when hit mode then go to the point you want. so it will round to how many digits you want.

Lets say you want it rounded to 9 places go

:fix 9

:disp i

or what ever you want Good luck

Rounding 3 to the nearest tens.

The process should always be the same.

Step 1 - identify the column in question.

Step 2 - go the the column immediately to the right of this column

Step 3 - if this number is 5 or more, add 1 to the column in question and make all numbers to the right 0, or if to the right of the decimal, eliminate them.

Step 4 - if this number is 4 or less, don't add 1 to the column in question and make all number to the right 0, or if to the right of the decimal, eliminate them.

To assist, I have written the number as 03.

Step 1 - Tens column is the 0.

Step 2 - Column immediately to the right is 3

Step 3 - Number is not 5 or more

Step 4 - Number is 4 or less, set the numbers to the right to 0

The answer is 0. The numbers -4, -3, -2, -1, 0, 1, 2, 3, and 4 when rounded to the nearest 10, all round to 0.

Good luck,

Paul

There are a few steps to rounding.

Identify the column that you are rounding.

Look to the digit immediately to the right.

If this digit is 5 or more, add 1 to the original column, otherwise don't add 1 to the original column.

Make numbers to the right of the original column 0.

Let's round this to the nearest 10s. The number immediately to the right is 8, so we add 1 to the 10s column and make the numbers to the right zeros. I get 4,320.

Good luck.

Step 1 - identify the column - hundreds - and check the number immediately to the right.

Step 2 - If the number is 5 or more, add 1 to the hundreds column, otherwise leave it the same.

Step 3 - set all numbers to the right of the hundreds column to 0.

a. 5,107 rounds to 5,100

b. 5,089 rounds to 5,100

c. 4,963 rounds to 5,000

d. 4,962 rounds to 5,000

Let me know if you have any questions.

Good luck,

Round up to 32.2. Round down to 32.1

Mar 01, 2015 | Office Equipment & Supplies

Not sure if this is your question, but, the way we usually round down from 5 and round up from 6. Example: 1.586 rounded to the nearest 100th would be 1.5**9 , **rounded to the nearest 10th would be 1.**6**... get it?

So, in your example, it would be : 40.9**8** = nearest 100th , 4**1.00** = nearest 10th , seeing as the **.9** rounded up to a whole number, thus **1** !!

Hope this helps !!

So, in your example, it would be : 40.9

Hope this helps !!

There is a round( function called **round(** . Example round(1/3,4) rounds fraction 1/3 to 4 decimal digits. You find the function in the CATALOG, or under MATH>NUM> 2:round(

Yes and here is how to do 1-var statistics and 2-var statistics. Please read the whole post. I assume
you
know the theory. I will show you the key strokes

For 1-Var statistics

Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.

Enter a number and press [=]. Cursor jumps to second number to enter.

Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.

**Press
[AC] key to clear the screen.**

Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.

Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.

To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics

To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

For 1-Var statistics

Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.

Enter a number and press [=]. Cursor jumps to second number to enter.

(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.

Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
