Float in Database to ? in .NET

Question

If you have a float in MSSQLServer, to what do you map this in .NET?

Can you convert it to Double or will you lose numbers?

Answer 1

SQLServer float and C#/VB double have the same representation. This is the correct mapping. What you don't want to do is map SQL Server float to C#/VB float as that may involve a loss of precision. SQL Server real maps onto C#/VB float.

T-SQL float and real type definitions can be found at MSDN. C# double definition can be found at MSDN as well, as can the float definition.
