How can I remove decimal places if all values to the right of a decimal  point are zeroes?

In a report I have 2 format  possibilities:
1. 12345.6789
2. 12345.0000

How can I  make #2  just a whole number due to all zeroes in decimals,  when displayed and keep #1 the same including the decimals?

The desired results would then look like this.
1. 12345.6789 (no change)
2. 12345 (now just a whole number)
If I havn't provided you enough info just ask.

=CInt(Fields!amt.Value)

that will turn the float into an interger (also round the number)

What data type they have?

because if you do this, the result is what you expect.


If they are varchar, can do this.


Cheers.
DECLARE @a FLOAT = 0.1111
DECLARE @b FLOAT = 1.0000

SELECT @a, @b

(No column name)	(No column name)
0,1111	                 1



---


DECLARE @a VARCHAR(10) = '0.1111'
DECLARE @b VARCHAR(10) = '123456.0000'

SELECT @a, LEFT (@b, CHARINDEX( '.', @b) - 1)

If you use CAST or CONVERT to make them INTEGER, you will loose the case

1. 12345.6789 (no change)

select case when cast(substring(cast(1234.1235 as varchar(12)),charindex('.',cast(1234.1235 as varchar(12)))+1,len(cast(1234.1235 as varchar(12)))-charindex('.',cast(1234.1235 as varchar(12)))) as int) = 0 then cast(1234.0000 as int) else 1234.6578 end

This is just example. Instead of static value, you can use your column name

Hi,

  I just used varchar(12). You can increase the size as per the length.

Just an improvement


DECLARE @a VARCHAR(10) = '0.1111'

DECLARE @b VARCHAR(10) = '123456.0000'



IF CAST(RIGHT(@a, LEN(@a)- CHARINDEX( '.', @a)) AS INTEGER)  = 0 

	print 'decimal'

else

	print 'integer'

	

	

IF CAST(RIGHT(@b, LEN(@b)- CHARINDEX( '.', @b)) AS INTEGER)  = 0 

	print 'decimal'

else

	print 'integer'

Hi,

My last


Cheers
DECLARE @table TABLE (value VARCHAR(20))

INSERT INTO @table
VALUES('0.1111')

INSERT INTO @table
VALUES('123456.0000')


SELECT CASE WHEN CAST(RIGHT(value, LEN(value)- CHARINDEX( '.', value)) AS INTEGER)  = 0 
			THEN LEFT (value, CHARINDEX( '.', value) - 1)
		ELSE
			value
		END AS value
	FROM @table

this will work for ssrs and only truncate the deciamal when there is 0000

=IIF(InStr(Cstr(Fields!amt.Value),"0000")<>0,cint(Fields!amt.Value),Fields!amt.Value)

I like the expression format above however, when I attempt to configure substituting amt with my field "quantity"  the entire expression is underlined in red

=IIF(InStr(Cstr(Fields!amt.Value),"0000")<>0,cint(Fields!amt.Value),Fields!amt.Value)

Also, "0000" can somtimes be "000" or "00" or "0"

Can we tweak this expression to make it work?

Ok need to take that value and convert it to text.

then need to get the text value right of the decimal  using instr.

then convert that value back to an number and see if it is 0

do you want the function?

=iif(instr(cstr(Fields!amt.Value),".")=0,Cint(Fields!amt.Value),Fields!amt.Value)

I tested this on 2008 r2

when you take the cstr(value) it truncates the deciamal and all the 0 when the value is .00000
(not sure why but you can test it)

so all we look for is the decimal if it still there we know what to do.

Excellent that is working correctly.

I discovered one more issue and that relates  to the #1 value which originally was stated as no change desired.  However, my notes tell me that value must be truncated to only 3 decimal places.

Origianlly I had that set through the tablix to be set to only 3 decimals but this will no longer work with the expression..

simply stated can we concanctenate an expression that will limit the decimal places to three which have > than 0 values.

For an example:

12345.6789 (4 decimal places) incorrect

Should read as:

12345.678 (3 decimal places) correct & desired

Okay here is an update on this issue,

So on the Tablix properties under Number you can set the Custom format on the cell.

0.###;(0.###) This will give you both a positive & a negative format of:
12345.001 or (12345.001)
0r with all zeroes:
0

The 3 pound signs allow for only 3 decimal places but if they are all zeroes it will return only a 0.
