There isn’t a direct equivalent, in that there are no built-in .NET types which allow you to specify the precision/scale explicitly as far as I’m aware. There’s no *fixed*-point type like NUMERIC.

`decimal`

and `double`

are the common floating point types in .NET, with `decimal`

implementing decimal floating point (like NUMERIC in T-SQL) and `double`

implementing binary floating point behaviour (like FLOAT and REAL in T-SQL). (There’s `float`

as well, which is a smaller binary floating point type.)

You should choose between `decimal`

and `double`

based on what values you’re going to represent – I typically think of “man-made”, artificial values (particularly money) as being appropriate for `decimal`

, and continuous, natural values (such as physical dimensions) as being appropriate for `double`

.
