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 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?

You can use NumberFormat class.
There are lot of threads available in this forum. Just search for the keyword 'NumberFormat'.

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,

How to set Decimal Point position from right to left Serial Read Evaluate Number within Range over RS-232

I am new to Labview, I am communicating with a TQ8800 Torque meter via RS-232. The 16 digit data stream is as follows:
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
Each digit indicate the following status :
D0 End Word
D1 & D8 Display reading, D1 = LSD, D8 = MSD
For example :
If the display reading
is 1234, then D8 to D1 is :00001234
D9 Decimal Point(DP), position from right to the left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D10 Polarity
0 = Positive 1 = Negative
D11 & D12 Annunciator for Display
Kg cm = 81 LB inch = 82 N cm = 83
D13 1
D14 4
D15 Start Word
I am using a modified version of the basic_serial_write_read.vi. I am attempting to parse the 16 digit data stream extracting out the number and whether it is positive or negative. I am having trouble with the decimal point placement. Is there an example that could help me with this? After the number is parsed I am then comparing it to see if it is within +/- 9.2 N cm. If it is then the test passes. I am outputing the data to a file. I have included the vi. Also how can I check for different units of the annunciator. Any help would be appreciated. Thank you.

What is the definition of the End Word? You will likely need to figure this out experimentally (the manual doesn't seem to define it). Whatever it is, you should set that as the termination character and enable the termination character. That will help you in keeping your messages in sync. Just tell the VISA Reads to read more than a message should be, something like 30 should work nicely.
The error you are seeing is a buffer overload. This means that the instrument is sending data to you faster than you can process it. So you need to figure out how to perform the read faster. File IO is slow. So you should put that into a seperate loop so that your loop does nothing but read the data from the port as quickly as the data comes in. Use a queue to send the data from the reading loop to the logging loop. This is known as a Producer/Consumer.
And here is a cleaned up version of your code. No need for your express VI or the formula node. Some other general cleaning up also done to make it easier to read.

How to increase Decimal Points for the BOM Component Quantity

Hi All,
While creating BOM:
Can anyone help me to know how i can increase the Decimal points for the BOM components quantity.
I can able to give only upto 3 decimal points, but the requirement is more than that.
I have increased the Decimal point value to 5 in transaction Code CUNI. but still it is allowing me to enter only upto three decimal places.
Thanks and Regards
Khadeer

Khadeer,
You would be better off changing the base quantity of the parent part. Instead of "1 EA parent contains .00003MG of component" you could say "100 EA parents contain .003MG of component".
Alternately, you could use different units of measure for your parent or component parts, which would be more suitable for the 3 place decimal limitation.
I agree with Anil in that if you elect to change the decimals from standard, you could end up with huge changes that will propagate through every module in the ERP. In my view, there is no need of this kind of headache.

How to delete decimal point and adding leading zeros....

Hi,
I have one requirement in the report i.e.
 Present Value : 44567.98
 Expected Value : 0000004456798
In the present Value how will I remove that decimal point and how to add those six ing zeros. I tried with CONVERSION_EXIT....but it is not giving. Help me...
Thanks in advance.
Regards,
Kumar.

Hi,
Use SPLIT and COMCATENATE fnctions.
Eg: split l_v at '.' into l_v1 l_v2
 concatenate l_v1 l_v2 into l_v.
For adding leading zeros
Use FM CONVERSION_EXIT_ALPHA_INPUT.
Eg:
data: tknum type vttk-tknum value '99156'.
call function 'CONVERSION_EXIT_ALPHA_INPUT'
 exporting
 input = tknum
 importing
 output = tknum.

How to restrict decimal point entry in numeric field?

Hi All,
There is a requirement from our client that, they cannot accept amount in decimals. That is, they cannot accept the cents, the amount that can be received from them is only in EURO and the same will be entered in the field. They want me to restrict the entry of a decimal point totally in the field, so that there requirement is fulfilled.
Is this possible? If yes let me know how?
If no, can you provide me justification, so that i can intimate the same to my client.

Dear Steve,
I had written in my first thread that, They want me to restrict the entry of a decimal point totally in the field.
If i use 9999 as format mask, then it still allows me to enter a decimal, but when the focus moves out of the field, it highlights the field and warns me "Field must be of form 9999".
But my requirment is to "Restrict the entry of decimal point totally @ runtime".

How to fix decimal point limit

Hi
how do i fix the decimal point digit.
for e.g
if the input number is 123.33
then it should conver it to 123.330
OR
if input 123
then it should convert it to 123.000
OR
if input 123.321456
then it should convert it to 123.321
Thanks in advance.

No that is not the solution.
But I found out a different solution. The following code will give me exact figure which I was looking for.
BigDecimal inputSize = new BigDecimal(12.3215)
inputSize.setScale(3, RoundingMode.FLOOR);
Thanks to all of you for your support
Ciao :-)

How to change decimal point in Rotate Tool.

Hi,
I use the rotate tool to design gauges, like clocks, a lot. I hold the ALT button and click on the center of my drawing and then a window pops up to enter in what degree I want my object to be. Currently the decimal point only allows for hundredths, ex. 45.25 degrees. Is there any way to change this to thousandths or even higher, ex. 45.25125? I've attached a screenshot to show you what I mean.
Any help would be appreciated!
Thanks,
Laura

Laura Belle,
When you enter the full decimal value, that should give you the right rotation whatever the truncated value is.
At least I hope that is still the case in your version.
You may test it as follows:
1) Create a square with W = H = 100;
2) Rotate thrice, each time inserting 33.333333 degrees, then rotate by -100 degrees;
3) Look at the W and H values;
4) Repeat 1) - 3), only with 33.33 degrees and see what you get.
You should get W = H = 100 in 3) and something like 100.017 to 100.018 in 4).

Is the data a number in string format?
with q as (select '12345' myNum from dual
union all select '45.78' from dual)
select case when instr(myNum, '.') > 0 then to_number(myNum) else
to_number(substr(myNum, 1, length(myNum) - 2) || '.' ||
substr(myNum, length(myNum) - 1)) end newNum from q
NEWNUM
123.45
45.78If not just use
with q as (select 12345 myNum from dual
union all select 45.78 from dual)
select case
when instr(myNum,'.')>0 then myNum
else myNum/100
end myNum
from q
MYNUM

How to put decimal points in your calculator for mac only on Xcode.

I need help. I created an app for calculating division, multiplication, addition & Subtraction. But everytime I divide 5 / 4, I get 1 without a remainder. The calculator app in OS X has a remainder when I calculated the division problem. I searched on the internet for help, but all of them are iOS tutorials. HELP!!!!!!

OK. But someday I'll be able to get these decimals in the calculator so that 5 divided 4 doesn't say 1, but says 1.1 (1.3 in the Calculator app in OS X.) Here's the code once again:
- (IBAction) getSum:(id)sender;
    int addend1, addend2, sum;
    addend1 = [mathField1 doubleValue];
    addend2 = [mathField2 doubleValue];
    sum = addend1 + addend2;
    [mathAns setDoubleValue:sum];
- (IBAction) getDiff:(id)sender;
    int minu, subtrah, diff;
    minu = [mathField1 doubleValue];
    subtrah = [mathField2 doubleValue];
    diff = minu - subtrah;
    [mathAns setDoubleValue:diff];
- (IBAction) getPro:(id)sender;
    int mulcand, mulpiler, pro;
    mulcand = [mathField1 doubleValue];
    mulpiler = [mathField2 doubleValue];
    pro = mulcand * mulpiler;
    [mathAns setDoubleValue:pro];
- (IBAction) getQuote:(id)sender;
    int numer, denom, quote;
    numer = [mathField1 doubleValue];
    denom = [mathField2 doubleValue];
    quote = numer / denom;
    [mathAns setDoubleValue:quote];
If this question has been answered, then I'll continue my Xcode development. If not, i'll have to throw my project in the trash. Leave me a suggestion.

Arithmatic Equation - How to change decimal point ?

Dear all,
I am very new to LabView. I am currently using LabView 7.1 for my project.
I am building a voltmeter reader. (attached is the vi file). The flow should be like, i am reading voltage from I/O card. Then, the voltage value (eq. 10 volt) is changed to percentage (for example 91%). I am using simple arithmatic icon (multiply and division). Then, these value will be written to a file (eq. voltage1.lvm).
The output file is something like this :

Here is one function called "Format into File" that has it. It is located to the top of the VI function block. Other file I/O VI's have it has well. If you right click on the function and select Edit Format String, it will pop up with a dialog box to help you create the format specifier.

Process order confirm_Goods movement_Qty consum. after decimal point not al

Sir,
I am doing process order confirmation (COR6), In which go to "Goods Movement "....and consume actual consumption qty...but when i put figure after decimal point, system does not allow...e.g 3.524 KG...System rounded figure which i put in BOM...e.g in bom 3.524 KG, but when i confirm (COR6) the order shows 4 KG....
Pl. help how to put decimal point...
Pl. not that in BOM , system allows to put decimal point qty, but in confirmation it does not allow...
Error message comes :
Only 0 decimal places are permitted for unit of measure KG
Message no. RU303
Rajesh

Sir,
We check in CUNI,
But in BOM, Decimal Point is allowed, but when we confirm the process order decimal place is not allowing...
If seems that is it any setting in process order ?...Because if any error in CUNI then it does not allow at BOM creation level also....

Using Decimal Points with Quantity in 11i

We are in apps 11.0.3 and going to migrate into 11i.
While making Returns to Vendor we cannot use decimal points in the place of quantity and we have to complete the transaction same as transaction completed in the PO receipt.
For ex: If I have case as following what is the solution in 11i?
PO Receipt for Item AAA quantity 100 Metric Ton
And due to some cases I have to return it 49.5m Metric Ton
In apps 11.0.3 I can make Returns with integer quantity only, but how I can manage this case in 11i?
null

In IP 5.0 Patchset I you can receive and return with decimal quantities.
