Data storage is a database, which is a collection of tables with typed columns. SQL Server supports different data types, including primitive types such as "Integer", "Float", "Decimal", "Char" (including character strings), "Varchar" (variable length character strings), binary (for unstructured blobs of data), "Text" (for textual data) among others. The rounding of floats to integers uses either Symmetric Arithmetic Rounding or Symmetric Round Down ("fix") depending on arguments: codice_1 gives 3.
