I have a FloatField which can have values like 22.33405, 33.567 etc. Now, I need to query using only upto 2 places after decimal like below
#find all objects with value equal to 22.33
ModelName.objects.filter(field = 22.33)
Is it possible to do so - can I round off or just take first 2 places after decimal?
thanks
try this
ModelName.objects.filter(field__gte=22.33, field__lt=(22.33 + 0.01))
or
ModelName.objects.filter(field__range=(22.33, 22.33 + 0.01))
range lookup
Not directly. If you need this level of accuracy then you should be using DecimalField.

Let's say I have a simple measure like this:
SimpleMeasure = MyTable[Column1]/MyTable[Column2]
Is it possible to have the number of displayed decimals dependent on the value? For example, if my measure calculates the number 500, then I don't want to see 500.00 but rather 500. However if my measure calculates 0.56, then I want to see the value displayed like that to two decimal places and not rounded to the number 1.
So a possible visualization table would look like this:
Store SimpleMeasure
00 10
01 18
02 0.67
03 6
Thank you in advance!
IF(
[SimpleMeasure] < 1, FORMAT([SimpleMeasure], "#,##0.##",
FORMAT([SimpleMeasure], "#,##0")
)
You can use the Switch() function. It will return the first True result. Put you values in a DESC order - start with the largest value, then come to a lower and then to the lowerest. For example :
Switch(
True
,[SimpleMeasure]<1,Round([SimpleMeasure],2) -- 0.655->0.66
,[SimpleMeasure]>999,Round([SimpleMeasure],-2) --1044->1000
,[SimpleMeasure]>499,Round([SimpleMeasure],-1) -- 505,5->510
,[SimpleMeasure]>99,Round([SimpleMeasure],0) -- 101,55->102
,[SimpleMeasure]>1,Round([SimpleMeasure],1) -- 99,43->99.4
)
Or/and you can use in the Switch() the Format() function, with or instead of Round() like:
Format([SimpleMeasure],"#,##0.#")
Or
Format(Round([SimpleMeasure],1),"#,##0.#")
-- Both of them Format() will return and show 99,43 as 99,4.
-- Placeholer # returns a digit or nothing.
-- Placegholder 0 returns a digit or 0.
Usage of Format() and Round() depends on your task. But for a selective Fomat you will need the Switch().
Hope, the answer will help you solve the case
I have a Actuals column like so:
ID | Airport
------------
A | 98.4
B | 98.0
C | 95.3
I'm attempting to format the numbers above into percentages for a front-end report. I have this written in a switch statement - for ease I'll just write the logic as an IF boolean.
example_measure =
VAR Nums = SELECTEDVALUES(Table[Actuals])
VAR FormatNums = IF(DIVIDE(ROUND(nums,1), nums) = 1,
format(nums,"0%"),format(nums,"0.0%")
-
RETURN
FormatNums
no matter what I do this always returns a number with a floating point value of 1f
so in my raw data of 98.0 I'm expecting the format to return "98%" rather than "98.0%"
the measures are used on individual cards, and are filtered so they can only ever show one value or blank, meaning they will only ever display one value on their own.
I've toyed with using if(nums = int(nums) which should evaluate to true for 98.0 but it I always get false.
There is a simpler way - just use built-in formatting codes:
Formatted Actuals =
VAR x = SELECTEDVALUE(Data[Actuals])
RETURN
FORMAT(x, "General Number") & "%"
Result:
Built-in style "General Number" handles your situation correctly, you just need to add % symbol to the formatted string. No need to test for whole numbers.
To convert a column/measure into percentage, you can simply divide the column by 100 and then format it as a percentage. Use the following steps:
Create a new column/measure: Perc_value = Table[Actuals]/100
Then go into the modelling tab, select the created column/measure and format it as a % and limit the number of decimal places to 0
This should give the view you are looking for. Hope this helps.
Edit:
You can use the below formula to achieve the desired result:
Column4 = IF('Table'[Column2]-ROUND('Table'[Column2],0)=0,FORMAT('Table'[Column2]/100,"0%"),FORMAT('Table'[Column2]/100,"0.0%"))
Replace Column2 withyour field and you should be good to go.
I want to find the minimum number with given conditions(is writer and is under probation), the below code works if D contains numbers, but how do I do it if the number is a part of a string, like a fraction for example? Like how do I use this formula if numbers in D look like "1/8", "31/688", "21/33", etc?
=MINIFS(D3:D1007, A3:A1007, "Writer", C3:C1007, "Probation")
I already have another formula that I use that calculates a decimal value given the fraction, If the fraction is in cell D21 then it would look like this:
=left(D21,find("/",D21)-1)/(right(D21,len(D21)-find("/",D21)))
but how do I apply this kind of formula in a minif/maxif?
I have attached a picture to show what I mean, what I'm trying to do is to put a formula in the passed/total column of package stats(probation), and it will get the lowest passed/total value out of the ones with that package name and importance level. as you can see, the entire writer package's pass rate is 5/8 because the lowest pass rate out of the writer package 5/8 is the lowest pass rate out people with package=writers and importance = probation. But at the moment I have to enter the 5/8s manually, I want it to be able to get it automatically using the formula I'm trying to figure out above.
try:
=ARRAYFORMULA(MIN(IF((A3:A="writer")*(C3:C="probation"),
IFERROR(REGEXEXTRACT(D3:D, "\d+")/REGEXEXTRACT(D3:D, "/(\d+)"), D3:D), )))
or to return fraction:
=ARRAYFORMULA(VLOOKUP(MIN(IF((A3:A="writer")*(C3:C="probation"),
IFERROR(REGEXEXTRACT(D3:D, "\d+")/REGEXEXTRACT(D3:D, "/(\d+)"), D3:D), )),
{IF((A3:A="writer")*(C3:C="probation"),
IFERROR(REGEXEXTRACT(D3:D, "\d+")/REGEXEXTRACT(D3:D, "/(\d+)"), D3:D), ), D3:D}, 2, 0))
also make sure fractions are formatted as plain text not date
I am trying to create an IF statement formula in excel that converts minutes to days and hours depending on the amount. Then rounds the value to 1 or 2 decimal points and adds the descriptive text (days, hours, etc) to the end
I have tried the following which converts and adds text but does not round:
=IF(L15>=1440, CONVERT(L15,"min","day") & CONCATENATE(L15," days"),
IF(L15>=60, CONVERT(L15,"min","hr") & CONCATENATE(L15," hours"),
IF(L15<=59, CONVERT(L15,"min","min") & CONCATENATE(L15," mins"))))
I would adjust your formula as follows and based on you wanting to round the final number
=IF(L15>=1440,ROUND(L15/1440,2)&" days",IF(L15>=60,ROUND(L15/60,2)&" hours",ROUND(L15,2)&" minutes"))
the ,2 in the ROUND function tell excel how many decimal places to calculate to. if format is set to general, trailing 0s will not be displayed. If you only want 1 decimal calculation then change the ,2 to ,1.
Using OLEDB from C++ I get DBTYPE_NUMERIC from DB2 for decimal fields and convert to DECIMAL like so (error checking omitted):
...
CDynamicAccessor* pAccessor = GetAccessor();
...
DBTYPE dbT=0;
pAccessor->GetColumnType(nIndex, &dbT);
if (dbT == DBTYPE_NUMERIC)
{
DB_NUMERIC* pNum = (DB_NUMERIC*)pAccessor->GetValue(nIndex);
DECIMAL dec;
DECIMAL_SETZERO(dec);
dec.sign = pNum->sign; // <--this comes back as 1 for positive fields and 0 for negative
dec.scale = pNum->scale;
memcpy(&dec.Hi32, pNum->val + 8, 4);
memcpy(&dec.Lo64, pNum->val, 8);
....
}
What I don't understand is why DB_NUMERIC::sign coming back as 1 for positive decimal fields in DB2 and 0 for negative. Is this correct behavior? By definition here it's the opposite for DECIMAL - 0 should be for positive.
Is it a db/field setting? In database everything looks positive. And if I set a value in db as negative it comes back positive. So the sign is turned on in the returning DB_NUMERIC structure for positives and turned off for negative. It's a reverse/inverse of what seems to be expected. What's wrong?
BTW: I can't find any docs on DB_NUMERIC that is in oledb.h anywhere.
Please help. Thanks a lot in advance!
Found an obscure doc in MSDN which confirms that DB_NUMERIC and DECIMAL treat the sign almost opposite ways.
