Setting precision of a float data type

I am trying to create a table with a column of type 'float(24)' in SQL Server 2000. When I do that via Enterprise Manager, the Precision field is grayed out, so I cannot change it from the default value of 53. I tried to create a table running a script like this:

CREATE TABLE [dbo].[MyTable] (
      [X] [float(24)] NULL
) ON [PRIMARY]

but I am getting an error "Cannot find data type float(24).". So I have no idea, how the precision can be defined for this data type. Looks like a simple issue, and because of this it's even more frustrating. Can anybody enlighten me, please?

Use Decimal(24,6) instead.  I don't believe float has precision.

What you are looking for is the data type real.

According to the documentation, you should be able to use float(24) to get a real, but perhaps that doesn't work in SQL Server 2000.

what kind of data do you want to store, actually?

Thank you. Yes, according to documentation it should be possible, and that's what irritates me. It's one of the most confusing pieces of documentation I've recently seen. I can declare a variable to be of type float(12), for example, and it works perfectly fine, but I cannot create a table column of this type. Oh, well...
In my case I'll have to go with 'real'.

lundnak:
Using Decimal(24,6) is not a solution because what I need is a number in floating point format.

I have to be able to store numbers in floating point format.
