May I ask for some advice, please?
I have for homework process data from file which has this structure:
"Time;Track;Force
s;mm;N
0,020;0,253;0,060
0,040;0,320;0,030
0,060;0,387;0,060
0,080;0,453;0,060
0,100;0,520;-0,000
0,120;0,587;0,030
0,140;0,654;0,030
0,160;0,721;-0,000
0,180;0,787;0,030
0,200;0,854;0,030
0,220;0,921;0,030
0,240;0,988;-0,000"
To load the data to matrix I use this command:
csvRead("Pene_1.txt",[';'],[],"string")
However my issue with this, is that the dates I would need in double because I will need to do some calculate with them, but in Europe a decimal point is used as the data separator instead of a decimal point. I would need to replace all of these decimal commas with decimal dots throughout the matrix. Please does anyone how to do it? Thanks you very much :)
by the way there I put whole file :)

Use csvRead("Pene_1.txt",';',',',"string") the third parameter ',' defines the decimal separator.

In my report I'm trying to remove the decimals without rounding. I'll be using this to set the minimum value in the vertical axis of the area chart.
So I tried =Format(98.56, "N0"), but this returns 99, which is incorrect. It should return 98.
I've been searching specifically for SSRS, but most of the results are for tsql.
My question: How can I remov decimals in SSRS without rounding?
Thanks
Try using "Floor". It effective rounds down to the nearest integer. You'll find this under the Math functions.
=Floor(Fields!Number.Value)
Note, there's also a Floor function in Transact-SQL that works the same way in case you need to do some of the processing in your SQL script.
Update based on request in comments
If you wanted to achieve the same result after the decimal point, all you need is a little algebra.
=Floor((Fields!Number.Value*10))/10
That should turn 99.46 into 99.4. Given that it shaves off the remainder, you could then tack on any additional zeroes you wanted.
I ended up converting to Int. The following expression in SSRS returns 98:
=Int(98.56)
I know the question is quite old, but as I ended up here having the same question I would like to share my answer:
While FLOOR and CEILING are fine if you take extra measures to handle numbers <0 or know they are always >=0, the easiest way to simply strip off the decimals is to use
=Fix(Fields!Number.Value)
FIX only returns the integer part of a number, without any rounding or transformation. For negative numbers Int rounds up.

Does anybody know which symbol is used by jscript's Number constructor to separate decimal places? Is it always a dot or dependent on locale?
I´m trying to create a number as follows:
Number(2,11):
But the result is NaN
I would bet that the symbol is always a dot but I would like someone to confirm that. Is there a way to indicate which symbol should be used for decimal places?
Thank you.
It's always a dot, though there are a number of other legal syntaxes

I have an application in which users are typing measured amounts. I would like to respect the precision they are entering when storing the values in MySQL, i.e. if they type 0.050 I don't want that to become 0.05 since that is loosing information on how exact the measurement was done. Is there a way other than storing the value as a string?
0.050 is equal to 0.05 . If you want 3 digits after comma, you have to implement this feature in application.
As per my knowledge for handling precision point we are using FLOAT, DOUBLE or DECIMAL data types. In your case if you are not using any function like SUM(),AVG(),etc then you can use VARCHAR.
Add always a "control" digit, lets say "1", save to database, then get data from database and always trim ONE time the "control" digit "1" from what you've got.
example:
user inputs 0,000050
save as 0,0000501
get the 0,0000501
trim the last "1" (only the last one be carefull)
k.i.s.s. people :D
edit: proper solution of course, add a column to store precision and right-pad zeroes if needed
In general, I have double values that I work with. I use them as double values and also as strings (in application code). I store them as Double in my MySQL database.
The problem I have is with trailing 0's. For example, the value I get is 10.60. This value gets truncated down to 10.6 which is not ok for me. I need that trailing 0.
I also need it to not add 0's. For example, if I got 10.60, it should not add 0's to be 10.600. I am not sure which data type fits my needs. It needs to be stored as the double value, but keep its trailing 0's, and not add any additional 0's.
Can anyone assist me in which data type to use?
I would store the double values in a double/real field only and not varchar so as to not lose any precision during conversion. Since the issue is only in application code, I would round them to the appropriate decimal places (using the ROUND() function) while retrieving from the database.
I have a SSRS report with full of number fields. I would like to have that to be displayed as in one decimal. i tried to use F1. it gives me only one decimal points in html rendering, but in excel exported version it shows 2 decimal points.
How can i have just one decimal point both ecxel and html rendering.
Please comment.
Thanks in advance

Use N1 as your Format Property setting. N denotes Numeric formatting, the 1 denotes the number of decimal places, so N2 would give you 102.02, for example. This should carry to excel as it is rendered in html.
Alternatively, you could use the format code #,##0.00, which will give you the thousands separator and two decimal places. '#' indicates optional characters, whilst '0' indicates mandatory characters (nulls will be replaced by '0.00').
in 2012 version: FormatNumber(Fields!col.Value,2)
Right click on the text box that contains the value you would like manipulate, select TEXT BOX PROPERTIES. Navigate to the Number tab, select Number and the # of Decimal places you want the box to allow for.
