use a select statement; how do you make this
44.8730084
into this
44.8 %
actually doesn't even have to be a percent ( % ) could simply
be a truncate of sorts to appear like this 44.8
any help, or direction on this would be great.
many thanks

Go to BOL and look up numeric data types . . .

BTW, 44.873 would round to 44.9, not 44.8 (this is the math guy in me coming out here) . . .

Ray is right. You would be getting 44.9 rather than 44.8
Start with this.
select ROUND(44.8730084,1) -- gives 44.9000000 as output
Or try this way.
declare @val float;
set @val = 44.8730084
select ROUND(@val,1,1) -- gives 44.8 as output
select ROUND(@val,1,0) -- gives 44.9 as output

thanks for the replies... the value
i gave was just a sample not the actual results coming out of the query.
and it wouldn't be just 'that' value; would be applied to any value returned from
the 'percent' column.
i'm not that great with tsql, but from the looks of it the examples apply to just
one value and not the range queried ( forgive me if i misunderstand )
any how; what about truncating the 52.2027837 to something like this
52.2
any ideas?
thanks in advance

select substring(cast(44.8730084 as varchar),1,4)+'%'

Did you read BOL like I suggested? (Not trying to dance around the answer -- just trying to encourage you to look it up and figure it out on your own before asking questions, which is highly encouraged in this forum.)
There are a number of data types that will do this for you. For example, try DECIMAL.
Try messing with the numbers (including the 4 and 1 in the decimal declaration) in this example in your SQL and see what it does for you . . .
declare @number decimal(4,1)
select @number = 10.2436
select @number

select substring(cast(44.8730084 as varchar),1,4)+'%'
Why would you want to convert to a varchar just to round a number off? String conversions are expensive operations.

is ok... is a very small db.
let me see what i can do with these examples.
thanks to all!

If you're trying to convert from a table, try playing with this example:
declare @temp table(thisval float)
insert into @temp values (23.61)
insert into @temp values (1234.13456143)
insert into @temp values (100.00001)
insert into @temp values (12.34)
insert into @temp values (3.14159)
insert into @temp values (10.01)
select cast(thisval as decimal(6,2)) from @temp
Note: if I'm not mistaken (and someone correct me if I'm wrong), it's generally not advisable to put a function into a SELECT statement, since it can use processor time.
