I write a Sql Query for some calculation

SQL

Declare @fltAdjQuantity as float
Set @fltAdjQuantity = 1.0714285714285714
select @fltAdjQuantity
select @fltAdjQuantity - 1

@fltAdjQuantity = 1.0714285714285714 and when I deducted it with (-1) It will give 7.1428571428571397E-2 instead of 0.0714285714285714 [1.0714285714285714 - 1 = 0.0714285714285714 ].

Please Help me i am waiting.....

There is nothing wrong. This is expected result, with expected accuracy. Don't forget, the calculations are approximate. You can also present the numeric values in the string form using format you need through double.ToString(string format). Please see also:

Hi,

SQL

Declare @fltAdjQuantity as float
Set @fltAdjQuantity = 1.0714285714285714
select @fltAdjQuantity
select @fltAdjQuantity - 1

I checked you above query and it is giving me 0.0714285714285714 which you need as an answer.

Pls elaborate your question.
