I would like to know if there is a function or some sort of way to round a number to lowest whole value. Something like floor, but to a specified increment like 10. So for example:
0.766,5.0883, 9, 9.9999 would all be floored to 0
11.84848, 15.84763, 19.999 would all be floored to 10
etc...
I'm basically looking to fit numbers in the ranges of 0, 10, 20, 30, etc
Can I also do it with different ranges? For example 0, 100, 200, 300, etc
Thank you.
You can do this with arithmetic and floor():
select 10*floor(val / 10)
You can replace the 10s with whatever value you want.

I am writing a model to calculate the maximum production capacity for a machine in a year based on 15-min data. As the maximum capacity is not the sum of the required capacity for all 15-min over the year, I want to write a piece of code that determines the maximum value in the list and then adds this maximum value and the three next consecutive values after this maximum value to a new variable. An simplified example would be:
fifteen_min_capacity = [10, 12, 3, 4, 8, 12, 10, 9, 2, 10, 4, 3, 15, 8, 9, 3, 4, 10]
The piece of code I want to write would be able to determine the maximum capacity in this list (15) and then add this capacity plus the three consecutive ones (8,9,3) to a new variables:
hourly_capacity = 35
Does anyone now the code that would give this output?
I have tried using the max(), the sum() and a combination of both. However, I do not get a working code. Any help would be much appreciated!
enter image description hereI want to round the figure of "Rate" if the decimal value becomes .5 or higher (For Example if 17.57 I want it as 18, if 20.98 I want it as 21)
On the other hand, if the decimal value becomes lower than .5 (For Example if 17.23 I want it as 17, if 20.49 I want it as 20)
I am attaching an image. Please let me know the condition.Thank you.
You just need use Round() function as below:
select round(86.54,0) //zero will fix in your case
Use round function
select round('19.6',0)

In DBeaver I have a table containing some GPS coordinates stored as Postgis LINESTRING format.
My questions is: If I have, say, this info:
LINESTRING(20 20, 30 30, 40 40, 50 50, 60 60, 70 70)
which built-in ST function can I use to get every N-th element in that LINESTRING? For example, if I choose 2, I would get:
LINESTRING(20 20, 40 40, 60 60)
, if 3:
LINESTRING(20 20, 50 50)
and so on.
I've tried with ST_SIMPLIFY and ST_POINTN, but that's now exactly what I need because I still want it to stay a LINESTRING but just with less points (lower resolution).
Any ideas?
Thanks :-)
Welcome to SO. Have you tried using ST_DumpPoints and applying a module % over the vertices path? e.g. every second record:
WITH j AS (
SELECT
ST_DumpPoints('LINESTRING(20 20, 30 30, 40 40, 50 50, 60 60, 70 70)') AS point
)
SELECT ST_AsText(ST_MakeLine((point).geom)) FROM j
WHERE (point).path[1] % 2 = 0;
st_astext
-------------------------------
LINESTRING(30 30,50 50,70 70)

ST_Simplify should return a linestring unless the simplification results in an invalid geometry for a lingstring, e.i., less than 2 vertex. If you always want to return a linestring consider ST_SimplifyPreserveTopology . It ensures that at least two vertices are returned in a linestring.

Hi I am not able to sort a column that contains decimals in a radgrid. When I sort, it only sorts by first number, like if sorting a string.
Ex: 1000, 12, 1300, 2189, 20
Instead of sorting like this:
12, 20, 1000, 1300, 2189
I am using EF4 and working with VS2012 in vb.net.
Any suggestions? this is my column:
I have written a code like below, my problem was sometimes I am getting same color for different segments in the piechart if the value came from the same range.
ref:
rdlc expression iif use?
my code sample
=SWITCH(Fields!ID__Share_of_Costs.Value <= 0.99, "Yellow",
Fields!ID__Share_of_Costs.Value <= 30, "Teal",
Fields!ID__Share_of_Costs.Value <= 60, "SteelBlue",
Fields!ID__Share_of_Costs.Value <= 100, "Crimson",
)
for eg: suppose my chart value is dynamic and it will come like 22 and 29, in this case the segment will show the same color (<= 30, "Teal",) as it is difficult to differntiate. Is there is any way to give different colors for each segment like no repeated color ?
Thanks in advance...cheers
It depends what do you mean by segment (range of values or particular value) or in other words is number of your segments limited?
If yes, then you could set up as much segments as you want with particular color.
If no, then write a custom function which will return hex value as your color.
