Round decimal number to two places

trying to round a decimal number to two places i.e. 1.98999 should round to 1.99.
-tried using math.round but it only rounds to nearest integer
-tried using decimalformat class but that converts to string, and cast wont allow me to convert from string back to double
*is there a round method that allows you to specify decimal places?
*or is there an easy method to cast a string back to a double?
any advice is appreciated:)

-tried using math.round but it only rounds to nearest integerI advise against rounding in most newbie situations. Usually it's the display of the variable you want to change.
-tried using decimalformat class but that converts to string, and cast wont allow me to convert from string back to doubleOf course cast won't allow you to convert back. If you wanted to do that you'd use Double.parseDouble(stringVar); But we don't know why you are doing all this converting in the first place.
*is there a round method that allows you to specify decimal places?
*or is there an easy method to cast a string back to a double?Advice: Forgetting all this fooha with rounding, what in essence are you trying to achieve? Why all of this number manipulation in the first place? It will affect what should be the best answer.

How to round decimal point to two places

Hi all, I have been tasked with creating a custom "calculator" for a client that uses a specific equation. The client inputs data into two Input Text fields and the result shows up in a dynamic text field. Is there any way I can limit the number of decimal places to two? Here is my code (which works, except for the decimal issue):
function onCalculate()
one = Number(number_one);
two = Number(number_two);
result_1 = ((one / 4) * (65 / (1 - 0.25))) + ((two / 0.5) * (65 / (1 - 0.25)));
Thanks in advance!!!!

What will often be done is the result is first multiplied by 100, then rounded to an integer, then divided by 100. So picking up from your last line where you calcvulate the result_1 value...
result_1 = Math.round(result_1*100)/100;

Round a number to 2 decimal places

Hi,
I have a computed value that returns 10 plus digits after the decimal place, exampe: 2.2482352941176.
What is the easiest way to edit this value in TestStand to return a number that is rounded up to 2 decimal places (2.25)?
Thanks & Regards,
Don1.
Solved!
Go to Solution.

One way to do this is to use the TestStand functions Str and Val. The %.2f rounds the number to 2 decimal places.
Val(Str(Locals.MyValue, "%.2f"))

Rounding off 2 decimal number

Hi,
How can i round up float number to two decimal number.
For example
Number is 45.987654532 then It should be rounded up to 45.98
Number is 45.987654546 then It should be rounded up to 45.99Appriciated sample souuce (If any)
Tanks in advance

You could have a look at String's format() method. The format strings are
described in detail here:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.htmlpublic class Round {
    public static void main(String[] args) {
        double number = 45.987654546;
        String roundStr = String.format("%.2f", number);
            // Rounded is 45.99
        System.out.println("Rounded is " + roundStr);
            // The same thing
        System.out.printf("Rounded is %.2f%n", number);
}Note: these methods generate rounded Strings from floating
point numbers. Also, they round to a string representing the "nearest"
number - your first example is a little hard to understand in this regard.

How can I create accurate decimal dimensions when creating a new document or using the art board in Illustrator CS6? When I type in a number with a decimal, it automatically rounds the number up.

How can I create accurate decimal dimensions when creating a new document or using the art board in Illustrator CS6? When I type in a number with a decimal, it automatically rounds the number up.

For my part you are welcome, sdowers.
Unfortunately, the uncertainty arising from the rounding has been up several times here in this forum.
I just came to remember a warning that needs to be given:
The rounding of the representation of a numerical value may be harmless in itself, but if you use it for any operation that changes the value, such as multiplication or whatever, things will go wrong because the operation will be made on the basis of the rounded value instead of the true value. So, as in your first case in post #2, 39.625 rounded to 39.63 will become 79.26 instead of 79.25.

Decimal Number Validation.

Hi All,
I'm working on Interface currently where I need to load data from flat file to db. I use the sql loader to load the data, but before I saved the data I need to validate certain fields. How i can validate do decimal number validation. For an example, 1.11 is valid and 1.111 is invalid (2 decimal level). When i do the validation i need to check the field so it contains 2 decimal points only. If i contains 3 decimal point the data is invalid. Appreciate if anyone can help me with this. Thanks alot.

1. Will you want to load only valid data ??
2. Fail the load if one such invalid data found?
you need to use WHEN clause functionality in the sql loader - foe examples pls visit -
http://psoug.org/reference/sqlloader.html
WHEN clause shud look something like following -
WHEN LENGTH(substr(:columnname,INSTR(:columnname,1,'.')+1,LENGTH(:columnname))) <=2Using above will load only records having one or two digits after the dot [upto 2 decimal]
Assumption - Column name what ever you are choosing shud have only one decimal [one dot]in its designated start and end places.
Hope this helps..

Need help with Rounding a number.

I have 3 cells each with a formula in them. Please bear with me while I try to explain this.
Cell D18 contains the formula: =Sum(L18/C5) (L18's value is 58, C5's value is 10), So the value of the cell is 5.8. I need this number to round properly to 6. It does visually on the spreadsheet.
Cell F18 contains the formula: =Sum(E18/F5) (E18=28, F5=8) So the actual value of F18 is 3.5 which is rounded to 4 visually on the spreadsheet.
Cell G18 contains the formula =Sum(D18+F18). (D18 visually displays 6, F18 visually displays 4, therefore G18 should display 10). G18 actually displays 9. For some reason the calculations are still based on the actual calculations of D18 & F18, instead of the rounded displayed numbers. How do I get G18 to display the correct number of 10, rather than the rounded down number of 9?
I'm sure there's a simple fix that I'm just not understanding. I hope I explained my problem well enough, I'd appreciate any help I can get. These numbers are to calculate insulin dosage, so I need to be sure the math is correct.
Thanks in advance for any help!

The explanation is that you don't understand what you are doing.
When you ask numbers to display 0 decimal, you don't ask it to round the contents but to display the rounded value.
A contents remains 3.6 but the display is 4
an other contents may be 3.6 too displaying 4
When you sum, you ask number to add the contents (3.6 + 3.6) which is 7.2 and you ask it to display the rounded value of this result. So you correctly see 7 not 8.
If you want to get what you described, you MUST force Numbers to round.
First,I don't understand how you may invent such a silly thing like =Sum(L8/C5)
You are asking Numbers to sum the result of the division L8/C5 to nothing.
The correct syntax would ask it to calculate the quotient, no less no more.
=L8/C5
but here we need to round so, in D18, enter
=ROUND(L8/C5,0)
in F18, enter
=ROUND(E8/F5,0)
In G18, =Sum(D18+F18) is silly too.
You are asking nummber to sum (D18+F18) and nothing.
The correct formula may be:
=SUM(D18,F18)
or
=D18+F18

Exception in two places of insert statment

Sure - use two different blocks. The code you posted doesn't have any BEGIN.
The proper structure is:
BEGIN
. . . put your first code here
EXCEPTION
. . . put your first exception handling here
END;
BEGIN
. . . put your second code here
EXCEPTION
. . . put your second exception handling here
END;If you need your code to quit after an exception in one of the blocks issue a RAISE in the exception handler for that block.
Depending on what each block does and what you want to save or rollback it is also common to use SAVEPOINTs for the blocks.
See SAVEPOINT in the SQL Language doc.
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_10001.htm
>
savepoint
Specify the name of the savepoint to be created.
Savepoint names must be distinct within a given transaction. If you create a second savepoint with the same identifier as an earlier savepoint, then the earlier savepoint is erased. After a savepoint has been created, you can either continue processing, commit your work, roll back the entire transaction, or roll back to the savepoint.
Example
Creating Savepoints: Example To update the salary for Banda and Greene in the sample table hr.employees, check that the total department salary does not exceed 314,000, then reenter the salary for Greene:
UPDATE employees
SET salary = 7000
WHERE last_name = 'Banda';
SAVEPOINT banda_sal;
UPDATE employees
SET salary = 12000
WHERE last_name = 'Greene';
SAVEPOINT greene_sal;
SELECT SUM(salary) FROM employees;
ROLLBACK TO SAVEPOINT banda_sal;
UPDATE employees
SET salary = 11000
WHERE last_name = 'Greene';
COMMIT;
>
For your use case you could create a SAVEPOINT before each of the blocks and then in the exception handlers issue a ROLLBACK to the appropriate SAVEPOINT before you exit the procedure.

How to get a decimal number from three single byte numbers

i'am in a difficult situation. I have motor which provides me the number of steps moved as three numbers of length one byte.I 'am attaching the program with this message. Here the commands from index 2-4 outputs will provide the number of steps moved. But these are numbers with a single byte length(<256). So how can I get the corresponding decimal number from these three single byte length numbers. please reply

Without knowing what motor you are using, I'm guessing that you probably need to use the Join Numbers to combine the bytes into a U32. The other option is to use the Type Cast function.

My quantity is showing with a decimal point and two spaces

When people are entering a quantity of 1 it is showing as 1.00. It is confusing my users because they think this is a price. How can I get rid of the decimal point and two spaces?

Hi,
I am not able to reproduce this problem with a number field. Are you using this field as a payment-quantity field?. If so, please check that the Quantity in your payment setting is linked the the right field.
We can do a quick test: create a new form from scratch, add one textfield, then on the field property panel select Type=number.
Select Test tab and click on the Test Web Form button
Enter a number and commit --> check if you get the decimal point and the spaces.
If you still have problem with this, let me know
Thanks,
Lucia

Please help me to merge two places.sqlite to get my old and New history at the same time, every time i rename my two places.sqlite to see my old and new history

Thank You all in Advance

You can't merge history otherwise then using Sync to store the history and bookmarks of one places.sqlite on the Sync server and then disconnect.<br />
Copy the second places.sqlite file to your Firefox profile folder with Firefox closed.
Then setup Sync once again using that account and merge the content on the Sync server with your computer.
