The ROUND function would work.
ROUND(<value>, 2, 1)

Sorry, forgot about the varchar.

So CAST(ROUND(CAST(<value> AS decimal), 2, 1) AS varchar)

Another option would be to use CHARINDEX to find the position of the period, add 2 to that value and then use LEFT:

LEFT(<value>, CHARINDEX('.', <value>) + 2)

Shaun_Kline is correct.   Slight correction though, adding percision and scale to the decimal
Declare @str varchar(10) = '123.456'

SELECT CAST(ROUND(CAST(@str AS decimal(5,2)), 2, 1) AS varchar) 

Open in new window

This does beg the obvious question though, why is a column with numeric values a varchar data type?

As you have posted this in javascript, I assume you want the javascript to pre-format for you and the code for that is:

var twoPlacedFloat = parseFloat(yourString).toFixed(2);

Based on the error you posted, I'm guessing you have non-numeric data (maybe empty strings or NULLs) in that field as well. You can use the ISNUMERIC function to filter out records that does not contain numbers in your field.
