Rounding minutes to nearest five.
Hi,
I have tried the various methods suggested on other forum messages but to no avail.
I have a GUI that acts as the client for a reminder system i am making for some coursework.
It contains a combo box with values for the user to select a time from, however the time is not displayed in the format i would like it to be.
I would like the current time from the instance of calendar i have created to be rounded to the nearest five up.
The code i have for the combo box at the moment is:
cal.set(cal.MINUTE, (int)Math.round((double)cal.MINUTE));
n=0;
int z = 0;
while(z<288)
cal.add( cal.MINUTE, n);
s = DateFormat.getTimeInstance(DateFormat.SHORT).format(cal.getTime());
time_cb.addItem(s);
n=5;
z++;
This code always sets the first value of the combo box to 10 minutes past the hour and increments it by five from there. This happened with all the other methods i tried from the other forums also.
I would like it to round to the nearest five the current time and increment by five from this time.
Thanks for your time and help.

Your first line is wrong. Your setting the calendar minutes field to
some random value, cal.MINUTE, which has nothing to do with the current minute. You need to do
Calendar c = new GregorianCalendar()
which automatically sets the current minute
cal.set(cal.MINUTE,
(int)Math.round((double)cal.MINUTE));
n=0;
int z = 0;

Rounding Time to nearest 30 minutes
Good day,
I'm looking for a way to round the time portion of a date value. My query needs to return the time of day, rounded to the nearest 30 minutes - top of the hour or bottom of the hour.
If sysdate is: 12/28/2009 11:08:19 AM
I need to see: 12/28/2009 11:00:00 AM
If sysdate returns: 12/28/2009 11:18:19 AM
I need to see: 12/28/2009 11:30:00 AM
Any help is appreciated.

Rounding time to nearest hourly quarter
I have several records like
2/19/2010 1:25:46.000000 PM
2/19/2010 1:40:46.000000 PM
2/19/2010 1:55:46.000000 PM
2/19/2010 2:10:46.000000 PM
I want to round them off to the nearest quarter like
2/19/2010 1:30:00.000000 PM
2/19/2010 1:45:00.000000 PM
2/19/2010 2:00:00.000000 PM
2/19/2010 2:15:00.000000 PM
Any ideas how I would do that? a trunc(col,'mi) only lets me round it to the minute..
Note that records are not necessarily in the 5 minute interval difference it can also be 7 minute difference or 4 minute difference from the nearest quarter...
so I can also have records like
SysUpTime 2/19/2010 10:31:00 PM
SysUpTime 2/19/2010 10:57:00 PM
SysUpTime 2/19/2010 11:31:00 PM
etc.

But OP asked for "*Rounding* time to nearest hourly quarter". Same applies to Aketi's solution which, BTW, which always bumps it up to next 5 min.In which case, just substitute "Round" for "Floor"!
Although thinking about it, you'd probably want to add seconds into the mix:

Rounding off to nearest whole number without condition
hi,
i want to round a real number to an integer value,,wihout any conditions like
10.01 should be 11
10.1 should be 11 and like that
is it posible to do it?
thanks in advance.
amitIt doesn't look like you are trying to round to the nearest whole number here. It looks like you are trying to find the smallest integer value that is greater than or equal to the real number. If so, you would want to use the CEIL function (i.e.
1 SELECT CEIL(10.01)
2* FROM dual
SCOTT @ hp92 Local> /
CEIL(10.01)

Formulae - rounding down to the nearest five
I am new to JAVA programming and not (yet) a brilliant mathematician. Can anybody tell me an algebra formula for rounding down to the nearest 5 (in 100)? Thanks in advance [email protected]
Your question is not very clear.
Still I think this would help
//begin
int remainder = number % 5 ;
//We get the remainder
number = number - remainder;
//Trim down to the lower value
if (remainder >= 3){
number = number + 5 ;
//If the remainder is 3 or more we should round to the higher value
//End of block
Hope this helps

Datepiker rounding seconds to nearest minute in presentation?
Hi all,
I have a presentation with a display-only, non-editable datepiker, that references an object variable of type Time.
The variable contains a full timestamp with date and time down to microseconds; however when the time gets displayed in my presentation, the seconds are always rounded to 00.
Has anyone encountered this or know how to deal with it?
Thanks!

Data usage rounded up to nearest GB in Bill summary; Cannot download details as spreadsheet
Two problems:
1. Bill summary misrepresents data usage, rounding up to the nearest GB, for one of our 4 lines.
2. Data detail "download to spreadsheet" does not work.
My account has 4 lines. I have an old Family Share plan (no longer available) for 700 minutes; a "feature" for unlimited text; and individual data plans for each of the 4 lines. My daughter has a 2 GB data plan.
Latest Verizon Wireless bill says my daughter used 1.0000000 GB of data. She didn't think so. I logged in to Verizon, went to "View Bill". then for the Bill Period: May 29, 2014 - June 28, 2014, I selected "Details for" > "DATA". I see all the usage by date and time; I can adjust the display from default "KB" to "MB". Then I clicked the link "Download to SpreadSheet ".
Unfortunately, I get a file with only one line, just the headers, no data:
"Date" "Time" "Usage Type" "Description" "Minutes" "Application Price" "Total"
As a workaround, I can select and copy the data on the web page, then paste it into a spreadsheet program. I added a "sum()" formula and found that she used only 325 MB, not 2 GB.Does the bill say she used 1 GB or 2 GB? You had mentioned them both.
As far as the usage, it's not too say she literally used that much but to say that she used that much or less. It may not matter since she has the 2 GB/$30 which means that you would be billed the same way either way.
Your inability to download the spreadsheet may be due to an issue with your browser. -
Rounding off to nearest value with formatNumber
Can I use the formatNumber tag to round my numeric value to the nearest value?
Like if it's 15.7 I would like to display 16
And if it's 15.2, I would like to display 15
I could successfully truncate by giving a patteren but Im not sure if I can round it off.

Rounding off to nearest decimal point
i have these values
35.2
35.3
35.4
35.5
35.7
35.8
35.9
36.0
i am looking for indexes closet 35.74 in my array. (which is index 4.)
i used the "round to nearest" function and it gave me 36.
which is index 7.
what other ways to get the right index?
Solved!
Go to Solution.You will always have some difficulties with rounding to a specific number of digits after the decimal point because of the way numbers are represented in binary. When expressed in binary 0.1 is an infinitely repeating expression. Regardless of the display the internal representation of the number always uses the maximum resolution for the data type (8 bytes for DBL).
So you need to be very careful to define exactly what you want. If you have an array of values (regardless of the way they are displayed) Then you can find the closest to a Test Value by subtracting Test Value from the array and finding the minimum of the absolute values of the differences.
Note that in the image below the same values are in Array and Array 2 with the display on Array 2 set for 20 siginficant digits.

Always round up to nearest whole in APO DP
Hi
there is a requirement to always round up data to nearest whole number. number should be always rounded above and not rounded down.
Example a value of 0.07 should be rounded to 1
a value of 1.25 should be rounded to 2
a value of 1.75 should be rounded to 2
a value of 1.07 should be rounded to 2
and so on
Is there a way i can achieve in APO DP by some settings/paramater/config/macro/exit etc etc - i am on SCM 7.0
Thanks,
TJTejinder
Try using the CEIL() function in a macro.

SQL for rounding to the nearest value
Hi All,
My Oracle DB version is 10g Release2 and also 11gR1
I have data like below, I need to write a SQL for the below requirement.
ID RANGE_LOW RANGE_HIGH
1 50 55
2 55 60
3 60 63
4 63 77
5 77 84 The requirement is like I need to check a value between the above range low and high then round it to the nearest value.
Say, for example if I have 68 then the value is rounded to 63 else if 74 then 77 else if its in the middle of two values (70) then rounded to the highest value, here its 77.
Please advice.Ashu_Neo wrote:

Connection goes on for five minutes / off for five minutes
I connected a new Airport Express today. Using Safari or Firefox, I have five great minutes with no problems whatsoever, then five minutes off. But the interesting fact is, iChat and Mail keep on working. It's just the browser. I tried with and w/out OpenDNS, and it's the same. Sometimes Mail stops as well, but iChat or Skype are always connected... Help!
One interesting thing to mention is that, when I run the diagnostics, all the lights are green and it says it appears to be working properly... but I can't surf the web.

Rounding minutes up or down when using a to_char function
Hi, this is my query: select (to_char(incident_date, 'HH24:MI')) Time from cla_event
Incident_Date column has a date and time in it. The above query pulls the time which is what I require. I do however want the hour to be rounded down if less than 30min and up if grater than 30min. For example 21:29 becomes 21:00 and 21:37 becomes 22:00.
This is just a single column in my query so I'm hoping for a simple solution if there is one.
Thanks!!!

Rounding up to nearest whole number question
I have a calculation script that sometimes returns a decimal result. How would I create a script that would round that decimal up to the next whole number? Anyone have any idea's?
okay, I am not very good with this. That command is new to me. Where would I place that script if I already have a javascript script in the calculate event of that numeric field I am trying to get rounded up?
I basically have the javascript code in the numeric fields calculate event set to
this.rawValue = subform1.numericField1.rawValue;
I tried putting your script on the change event hoping I could use formCalc there but get a error when testing saying Ceil is not defined. Thanks -
