Hello,

I am doing this small exercise.

declare @No decimal(38,5);
set @No=12345678910111213.14151;

select @No*1000/1000,@No/1000*1000,@No;

Results are:

12345678910111213.141510    
12345678910111213.141000    
12345678910111213.14151

Why are the results of first 2 selects different when mathematically it should be same?
