Precision Lost On Substracting Two Floats

Hi, first than nothing the query, I'm on sqlserver 2000:

--------------------------------------------------------------------------------------------------------
declare @ordered float
declare @convertion float

set @ordered = 49.0
set @convertion = 24.0

SELECT
CAST((@ordered / @convertion) AS float) as colA,
CAST((@ordered / @convertion) AS INT) as colB,

cast(CAST((@ordered / @convertion) AS float) - CAST((@ordered / @convertion) AS INT) as float) as [colA - colB],

ABS(CAST((@ordered / @convertion) AS float) - CAST((@ordered / @convertion) AS INT)) * @convertion as [The reminder]

--------------------------------------------------------------------------------------------------------

If you run that you'll get this result:

colA colB colA - colB The reminder
2.04166666666667 2 0.0416666666666665 0.999999999999996

You'll notice the workaround to get the decimal part of a number, if you wonder why its because sql2000 in the operand % only supports integers. Anyway, try on your calculator ( 2.04166666666667 - 2 ) it probably answer: 0.04166666666667.

BUT SQL NOT! you see how the result is amazingly 0.0416666666666665 ????

Does anybody knows a solution for this??? What am I doing wrong???

If you try the query but instead of 49.0 use 25.0, it returns the correct value !!.

I really appreciate any comment about this.
