What is data type integer in access?

Integers in Access come in 1, 2 and 4 byte varieties. The single byte number is named Byte (Range 0-255), the two-byte number is named Integer (-32768 to 32767) and then there is the Long Integer (-2 billion to 2 billion). Decimal numbers are so called fixed point numbers.

What are the consequences of changing a field size in a database?

Changing the Field Size

  • Changing the field size reduces data-entry errors.
  • Access can process smaller field sizes more quickly.
  • Smaller field sizes require less hard-drive storage space.

Explicitly declares a literal value as a LongLong. This is required to declare a LongLong literal that is larger than the maximum Long value. If you don’t explicitly declare the value, Access converts it to a Double. Converts a simple expression to a LongPtr. This is valid on 64-bit platforms only.

When to use the long integer data type?

Tip: Use the Long Integer data type when you create a foreign key to relate a field to another table’s AutoNumber primary key field. Single — For numeric floating point values that range from -3.4 x 1038 to +3.4 x 1038 and up to seven significant digits.

Can a integer literal be given an extended integer type?

If the value of the integer literal is too big to fit in any of the types allowed by suffix/base combination and the compiler supports extended integer types (such as __int128) the literal may be given the extended integer type — otherwise the program is ill-formed.
