Pls help me on this. In QotD, question posted on Aug 6 on ROWCOUNT, the answer in infinite loop. ie, the condition @i <> 1 always is true . But another sample query as shown below gives expected result which contradicts from while loop.

DECLARE @i float
set @i = .9
set @i = @i + .1

-- Query 1
if @i <> 1
print 'Yes'
print 'No'

Answer: No

-- Query 2
if @i = 1
print 'Yes'
print 'No'

Answer: Yes

Can anyone pls explain on difference in this two.
