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

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.

Take this equation y = 3x + 4

As written x can be any value, and y depends on what that is. So y is the dependent variable here.

Of course you can write it the other way round, x = (y-4)/3 and then it appear that x is the dependent variable.

So in modelling a real situation it is important to arrange things so that the truly independent variable is modelled by "x", on the RHS

Say you were modelling fuel consumption as a function of speed. It becomes obvious that fuel consumption depends quite a bit on speed, so it should be the "y" variable.

The Entities in java are slightly different. I adore them being included (finally).

float bigNum = 123456.789012;

String pattern = String.format( "%10.2f is my magic number%n", bigNum);

System.out.println( pattern);

or

System.out.println(

String.format( "%10.3f", bigNum) );

the "decimal place" is the rounding.

lead off with a zero to get leading zeroes

String.format("%03.2f", bigNum));

if I want evenly spaced columns, I have to construct an Object[] array

array[0] = salaryAmt;

array[1] = hourly Rate;

array[2] = "Cowboy Bob";

System.out.println(

"%5.2f,%3.2d,%s%n, array);

Here you will get more information about java string format.

Your Texas Instruments calculator has a built-in printer for producing a permanent record printout of

your calculations with negative numbers printed in red. A big, easy-to-read display also enables you to

check entries or perform quick calculations without printing.

GETTING STARTED

OFF ON PRT IC GT

POWER

1. Connect the calculator to a proper power outlet (110-120V or 220-240V

where available).

2. The calculator is turned on by setting the POWER switch to the PRT

position.

Inserting the paper (see illustrations 1, 2, 3, and 4 on page ii).

1. Turn on the calculator.

2. Open the printer compartment cover by pressing down on its front edge and sliding it back in the

direction of the arrow.

3. Fit the roll of paper on the holder so that it unrolls from the bottom, with the loose end toward the

calculator.

4. Cut the end of the paper squarely and insert it firmly into the printer slot on the back of the

calculator.

5. Press & until the paper is in the printing position.

Replacing the ink roller (see illustrations 5 and 6 on page ii)

1. Turn the calculator off and tear off the excess paper.

2. Remove the printer cover by pressing down on both sides of the front edge and sliding back in the

direction of the arrow.

3. Remove the old ink roller by lifting it with the removal tab.

4. Insert the new ink roller into the compartment and press down gently until it snaps into place. Close

the printer compartment.

Note: The old ink rollers should not be refilled. Replacement rollers can be obtained from your local

retailer. The warranty does not cover ink roller replacement.

Truncates the result to the selected number of decimal places.

Rounds the result up or down according to its value. For example, when the

DECIMAL switch is set to 2, the result is rounded up if the third decimal

position is 5 or more and rounded down if it is 4 or less.

Rounds the result up to the selected number of decimal places.

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.

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

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.

Use the Math.Round() function. It takes two arguments, the first is your number or a variable holding your number and the second is the number of decimal places. This will only round to fractions of a whole number though and you need to round to the nearest 10. So divide your number by 10 before you round to shift the decimal place once to the left and multiply by 10 again afterwards to shift it back again.

answer = Math.Round(32.1 / 10, 0) * 10

answer = Math.Round(32.1 / 10, 0) * 10
